• Installing mongrel service on Windows 2008

  - by akirekadu

  We use InstallAnywhere to install our product. One of the components that it needs to install is mongrel. IA invokes the following command line during installation: mongrel_rails service::install -N service-1 -D "Service 1" -c "C:\app_dir\\rails\rails_apps\service-1" -p 19000 -e production Apprently under the hoods "sc create..." is used. The installation works great on Windows 2003. On Windows 2008 though this operation requires elevated privileges. When I login as local administrator (ie 'local-machine\administrator' user), the installation works just fine. However, when I login as a domain user that is part of local administrators group, the services fails to install with error "access is denied". How can I make it possible to install the product without having to login as local administrator? Thanks! Couple of notes I would like to add. One solution I tried is to execute the installer as administrator. The service does get installed. However, it creates another problem. An embedded 3rd party product and its files get installed with admin only rights. So we do need to run the installer as logged in user.

• php remove button keeps retreiving posted information

  - by Doug

  Hi every1! im quickly finding im quite the beginner to php, so please bare with me! I have a quick problem, I have a remove button for a shopping cart and the code works for it everytime except for the last product thats in the cart. If a person pushes the addtoCart button the URL is reloaded with ?buyproduct=$productNumber and when the remove button is pushed the product is removed. Right so everything is good, but when you try to remove the last item, it keeps reading the product thats in the URL. so the quantity remains 1 for the current $productNumber. i've tried adding the action in the form method tag so that the page reloads without the ?buyproduct=$productNumber, which does work however there are page numbers and sections that were also in the URL and these get reset also. i know the remove is working because once the ?buyproduct=$productNumber is gone from the URL (which can happen for example if they go to another section in the catalog) then the cart can be completely emptied. Thank you so much ahead of time for any1's help, I've used this site before and you guys are genius's!

• Use SQL Result to Query second time and grab more results via php

  - by maxwell

  I am grabbing a list of school names from a database. When the user clicks on the school name, i want the code to fetch 2-3 other attributes related to the school name that the user has clicked on. My code for the single school name list: $query = mysql_query("Select schoolname, product, username, password from credentials c join products p on p.productid = c.productid join schools s on s.schoolid = c.schoolid join icons i on i.productid = p.productid order by s.schoolname"); echo '<ul>'; while($row = mysql_fetch_array($query)) { echo "<li> <a href='#'>" . $row['schoolname'] . "</a> </li>"; } echo ''; Current Output: School A School A School B School B School B School C School C Expected Output: School name displayed only once (distinct won't work because each school name has 2-3 product credentials School A School B School C Ability for User to click on a school. then the school names underneath will move down (toggle effect) and user can see product, username and password displayed for the school clicked (for example: user clicked on School A) School A productname1, username, password productname2, username, password School B School C

• Sorting, Filtering and Paging in ASP.NET MVC

  - by ali62b

  What is the best approach to implement these features and which part of project would involved? I see some example of JavaScript grids, but I'm talking about a general approach which best fits the MVC architecture. I've considered configuring routes and models to implement these features but I don't have a clear idea that if this is the right approach to implementing such features. On the one hand, I think if we put logic in routes (item/page/sort/), we would have benefits like bookmarking and avoiding JavaScript. On the other hand if we use JavaScript grids, we can have behavior like the old school grid views in ASP.NET web forms. I find that using HTML helpers may be useful for paging, but have no idea if they are good for sorting or not. I've looked at jQuery, tableSorter and quick search plug-ins, but they work just on the currently-fetched data and won't help in real sorting and filtering that may need to touch the database. I have some thoughts on using these tools side by side with AJAX to get something which works, but I have no idea if there are similar efforts done yet anywhere. Another approach I looked at was using Dynamic Data on web forms, but I didn't find any suggestions out there as to whether or not it is a good idea to integrate MVC and DD. I know implementing filtering and sorting for an individual case is simple (although it has some issues like using Dynamic LINQ, which is not yet a standard approach), but creating a sorting or filtering tool which works in all cases is the idea I'm looking for. (Maybe this is because I want have something in hand when web form developers are wondering why I'm writing same code each time I want to implement a sort scenario for different Entities).

• Updating / refreshing a geojson layer

  - by Ozaki

  TLDR My geoJSON layer will display the vector mark but will not destroy the features or re add the features in causing a moving / updating look to the OpenLayers map. Hey S O. I have a geojson layer set up as follows: //GeoJSON Layer// var layer1 = new OpenLayers.Layer.GML("My GeoJSON Layer", "coordinates", {format: OpenLayers.Format.GeoJSON, styleMap: style_red}); My features are set up as follows: var f = new OpenLayers.Feature.Vector(null,style_red); var style_red = OpenLayers.Util.extend({}, layer_style); style_red.strokeColor = "red"; style_red.fillColor = "black"; style_red.fillOpacity = 0.5; style_red.graphicName = "circle"; style_red.pointRadius = 3.8; style_red.strokeWidth = 2; style_red.strokeLinecap = "butt"; and my layer updating function: function UpdateLayer(){ var p = new OpenLayers.Format.GeoJSON({ 'internalProjection': new OpenLayers.Projection("EPSG:900913"), 'externalProjection': new OpenLayers.Projection("EPSG:4326") }); var url = "coordinates.geojson"; OpenLayers.loadURL(url, {}, null, function(r) { var f = p.read(r.responseText); map.layers[1].destroyFeatures(); map.layers[1].addFeatures(f); }); setTimeout("UpdateLayer()",1000) } Any idea what I am doing wrong or what I am missing?

• Comparing values from a string in a MySQL query

  - by bellesebastien

  I'm having some trouble comparing values found in VARCHAR fields. I have a table with products and each product has volume. I store the volume in a VARCHAR field and it's usually a number (30, 40, 200..) but there are products that have multiple volumes and their data is stored separated by semicolons, like so 30;60;80. I know that storing multiple volumes like that is not recommended but I have to work with it like it is. I'm trying to implement a search by volume function for the products. I want to also display the products that have a bigger or equal volume than the one searched. This is not a problem with the products that have a single volume, but it is a problem with the multiple volume products. Maybe an example will make things clearer: Let's say I have a product with this in it's volume field: 30;40;70;80. If someone searched for a volume, lets say 50, I want that product to be displayed. To do this I was thinking of writing my own custom MySQL function (I've never this before) but maybe someone can offer a different solution. I apologize for my poor English but I hope I made my question clear. Thanks.

• Help understanding the Single Responsibility Principle

  - by user204588

  I'm trying to understand what a responsibility actually is so I want to use an example of something I'm currently working on. I have a app that imports product information from one system to another system. The user of the apps gets to choose various settings for which product fields in one system that want to use in the other system. So I have a class, say ProductImporter and it's responsibility is to import products. This class is large, probably too large. The methods in this class are complex and would be for example, getDescription. This method doesn't simply grab a description from the other system but sets a product description based on various settings set by the user. If I were to add a setting and a new way to get a description, this class could change. So, is that two responsibilities? Is there one that imports products and one that gets a description. It would seem this way, almost every method I have would be in it's own class and that seems like overkill. I really need a good description of this principle because it's hard for me to completely understand. I don't want needless complexity.

• Does Team Foundation support cross-app workitem groups?

  - by drachenstern

  We're currently using Visual Source Safe and BugNet and looking to migrate up and away from VSS. I've been pushing for either SVN ( a) we're an ASP.NET shop, b) DCVS is not an option - no matter how much I like Hg ;-) or TFS. Well we finally got a new dev server, so I talked the boss into installing TFS on it (30 day trial). In the meantime, we had started experimenting with FogBugz. We really like FogBugz for about 80% of what we want to do, and the other 20% is probably stuff that we don't know what we want. I'm pushing for TFS because it allows for IDE integrated (mostly) everything. He's pushing for FogBugz because he can group tasks by customer and then project and manage everything from one dashboard. (which means I lose most of my IDE integration - no huge loss I agree) Does TFS support a single dashboard that would span all our solutions (in this case each solution is a full app that we sell to a vertical market client) and let us assign workitems to each solution-spanning-group? So for instance I think we envision something like this: PROJECT1 - Bugtracker and workitems PROJECT2 - Bugtracker and workitems PROJECT3 - Bugtracker and workitems CUSTOMER1 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT2) CUSTOMER2 - Deployment schedules, required features, specific notes (Uses PROJECT2, PROJECT3) CUSTOMER3 - Deployment schedules, required features, specific notes (Uses PROJECT1, PROJECT3) Hopefully that makes sense. naturally it's more complicated than this but I think I've given the details enough to paint a picture. I offered the option of creating dummy projects per customer but he doesn't like that and it doesn't really give us the single dashboard view that we're hoping to end up with (and that FogBugz as we've sorta implmented things does do now). Has anyone got a good suggestion on a management app that would accomplish what both of us want?

• How to get SQL Function run a different query and return value from either query?

  - by RoguePlanetoid

  I need a function, but cannot seem to get it quite right, I have looked at examples here and elsewhere and cannot seem to get this just right, I need an optional item to be included in my query, I have this query (which works): SELECT TOP 100 PERCENT SKU, Description, LEN(CONVERT(VARCHAR (1000),Description)) AS LenDesc FROM tblItem WHERE Title = @Title AND Manufacturer = @Manufacturer ORDER BY LenDesc DESC This works within a Function, however the Manufacturer is Optional for this search - which is to find the description of a similar item, if none is present, the other query is: SELECT TOP 100 PERCENT SKU, Description, LEN(CONVERT(VARCHAR (1000),Description)) AS LenDesc FROM tblItem WHERE Title = @Title ORDER BY LenDesc DESC Which is missing the Manufacturer, how to I get my function to use either query based on the Manufacturer Value being present or not. The reason is I will have a function which first checks an SKU for a Description, if it is not present - it uses this method to get a Description from a Similar Product, then updates the product being added with the similar product's description. Here is the function so far: ALTER FUNCTION [dbo].[GetDescriptionByTitleManufacturer] ( @Title varchar(400), @Manufacturer varchar(160) ) RETURNS TABLE AS RETURN ( SELECT TOP 100 PERCENT SKU, Description, LEN(CONVERT(VARCHAR (1000),Description)) AS LenDesc FROM tblItem WHERE Title = @Title AND Manufacturer = @Manufacturer ORDER BY LenDesc DESC ) I've tried adding BEGINs and IF...ELSEs but get errors or syntax problems each way I try it, I want to be able to do something like this pseudo-function (which does not work): ALTER FUNCTION [dbo].[GetDescriptionByTitleManufacturer] ( @Title varchar(400), @Manufacturer varchar(160) ) RETURNS TABLE AS BEGIN IF (@Manufacturer = Null) RETURN ( SELECT TOP 100 PERCENT SKU, Description, LEN(CONVERT(VARCHAR (1000),Description)) AS LenDesc FROM tblItem WHERE Title = @Title ORDER BY LenDesc DESC ) ELSE RETURN ( SELECT TOP 100 PERCENT SKU, Description, LEN(CONVERT(VARCHAR (1000),Description)) AS LenDesc FROM tblItem WHERE Title = @Title AND Manufacturer = @Manufacturer ORDER BY LenDesc DESC ) END

• Django LFS - custom views

  - by owca

  For all those ligthning fast shop users. I'm trying to implement my own first page view that will list all products from shop ( under '/' address). So I have a template : {% extends "lfs/shop/shop_base.html" %} {% block content %} <div id="najnowsze_produkty"> <ul> {% for obj in objects %} <li> {{ obj.name }} </li> {% endfor %} </ul> </div> {% endblock %} and then I've edited main shop view : from lfs.catalog.models import Category from lfs.catalog.models import Product def shop_view(request, template_name="lfs/shop/shop.html"): products = Product.objects.all() shop = lfs_get_object_or_404(Shop, pk=1) return render_to_response(template_name, RequestContext(request, { "shop" : shop, "products" : products })) but it just shows nothing. When I do Product.objects.all() query in shell I get results. Any ideas what could cause the problem ? Maybe I should filter products with 'active' status only ? But I'm not sure if it can influence all objects in any way.

• Calling webservice via server causes java.net.MalformedURLException: no protocol

  - by Thomas

  I am writing a web-service, which parses an xml file. In the client, I read the whole content of the xml into a String then I give it to the web-service. If I run my web-service with main as a Java-Application (for tests) there is no problem, no error messages. However when I try to call it via the server, I get the following error: java.net.MalformedURLException: no protocol I use the same xml file, the same code (without main), and I just cannot figure out, what the cause of the error can be. here is my code: DOMParser parser=new DOMParser(); try { parser.setFeature("http://xml.org/sax/features/validation", true); parser.setFeature("http://apache.org/xml/features/validation/schema",true); parser.setFeature("http://apache.org/xml/features/validation/dynamic",true); parser.setErrorHandler(new myErrorHandler()); parser.parse(new InputSource(new StringReader(xmlFile))); document=parser.getDocument(); xmlFile is constructed in the client so: String myFile ="C:/test.xml"; File file=new File(myFile); String myString=""; FileInputStream fis=new FileInputStream(file); BufferedInputStream bis=new BufferedInputStream(fis); DataInputStream dis=new DataInputStream(bis); while (dis.available()!=0) { myString=myString+dis.readLine(); } fis.close(); bis.close(); dis.close(); Any suggestions will be appreciated!

• How to query two tables based on whether or not record exists in a third?

  - by Katherine

  I have three tables, the first two fairly standard: 1) PRODUCTS table: pid pname, etc 2) CART table: cart_id cart_pid cart_orderid etc The third is designed to let people save products they buy and keep notes on them. 3) MYPRODUCTS table: myprod_id myprod_pid PRODUCTS.prod_id = CART.cart_prodid = MYPRODUCTS.myprod_pid When a user orders, they are presented with a list of products on their order, and can optionally add that product to myproducts. I am getting the info necessary for them to do this, with a query something like this for each order: SELECT cart.pid, products.pname, products.pid FROM products, cart WHERE products.pid = cart_prodid AND cart_orderid=orderid This is fine the first time they order. However, if they subsequently reorder a product which they have already added to myproducts, then it should NOT be possible for them to add it to myproducts again - basically instead of 'Add to MyProducts' they need to see 'View in MyProducts'. I am thinking I can separate the products using two queries: Products never added to MyProducts By somehow identifying whether the user has the product in MyProducts already, and if so excluding it from the query above. Products already in MyProducts By reversing the process above. I need some pointers on how to do this though.

• Will rel=canonical break site: queries ?

  - by Justin Grant

  Our company publishes our software product's documentation using a custom-built content management system using a dynamic URL namespace like this: http://ourproduct.com/documentation/version/pageid Where "version" is the version number to which the documentation applies, and "pageid" is a unique string which identifies that page in our back-end content management system. For example, if content (e.g. a page about configuration best practices) is unchanged from version 3.0 and 4.0 of our product, it'd be reachable by two different URLs: http://ourproduct.com/documentation/3.0/configuration-best-practices http://ourproduct.com/documentation/4.0/configuration-best-practices This URL scheme allows us to scope Google search results to see only documentaiton for a particular product version, like this: configuration site:ourproduct.com/documentation/4.0 But when the user is searching across all versions, we don't want Google to arbitrarily choose one of the URLs to show in results. Instead, we always want the latest version to show up. Hence our planned use of rel=canonical so we can proscriptively tell Google which URL we want to show up if multiple versions are being searched. (Users who do oddball things like searching 2 versions but not all of them are a corner case, so we don't care which version(s) show up in that case-- the primary use-cases we care about is searching one version or searching all versions) But what will happen to scoped searches if we do this? If my rel=canonical URL points to version 4.0, but my search is scoped to 3.0, will Google return a result? Even if you don't know the answer offhand, do you know a site which uses rel=canonical to redirect across folders in a URL namespace. If so, I could run a few Google searches and figure out the answer.

• Examples of monoids/semigroups in programming

  - by jkff

  It is well-known that monoids are stunningly ubiquitous in programing. They are so ubiquitous and so useful that I, as a 'hobby project', am working on a system that is completely based on their properties (distributed data aggregation). To make the system useful I need useful monoids :) I already know of these: Numeric or matrix sum Numeric or matrix product Minimum or maximum under a total order with a top or bottom element (more generally, join or meet in a bounded lattice, or even more generally, product or coproduct in a category) Set union Map union where conflicting values are joined using a monoid Intersection of subsets of a finite set (or just set intersection if we speak about semigroups) Intersection of maps with a bounded key domain (same here) Merge of sorted sequences, perhaps with joining key-equal values in a different monoid/semigroup Bounded merge of sorted lists (same as above, but we take the top N of the result) Cartesian product of two monoids or semigroups List concatenation Endomorphism composition. Now, let us define a quasi-property of an operation as a property that holds up to an equivalence relation. For example, list concatenation is quasi-commutative if we consider lists of equal length or with identical contents up to permutation to be equivalent. Here are some quasi-monoids and quasi-commutative monoids and semigroups: Any (a+b = a or b, if we consider all elements of the carrier set to be equivalent) Any satisfying predicate (a+b = the one of a and b that is non-null and satisfies some predicate P, if none does then null; if we consider all elements satisfying P equivalent) Bounded mixture of random samples (xs+ys = a random sample of size N from the concatenation of xs and ys; if we consider any two samples with the same distribution as the whole dataset to be equivalent) Bounded mixture of weighted random samples Which others do exist?

• ECM (Niche Vs Mass Market)

  - by Luj Reyes

  Hi Everyone, I recently started a little company with a couple of guys. Ours is the typical startup, a lot of ideas, dreams, talent and work hours :P. Our initial business plan was to develop a DM (Document Manager) with several features found on DropBox and other tools but with a big differentiator. Then we got in the team this Business Guy (I must say that several of us could be called 'Business Guys' but we are mainly hackers, he is just Another 'Networking Guy'), and along with him came this market analysis for a DM aimed at a very specific and narrow niche. We have many elements to believe in his market study and the idea is the classic "The market is X million, so if we grab a 10%...", and the market is really there to grab because all big providers deemed it too little and fled, let's say that the market is 5 million USD and demand very specific features. If we decide to go for this niche product we face a sales cycle of about 7 months, and the main goal of these revenue is to develop more ambitious projects. (Institutional VC is out of the question if you want to keep a marginal ownership of your company in my country). The only overlap between the niche and the mass market product features is the ability to store documents; everything else requires that we focus all of our efforts towards one or the other. I've studied a lot about the differences between Mass and Niche Markets, but I want to hear from people with actual experience. So everything comes down to this: If you have a really “saleable” idea what is the right thing to do: to go for the niche or go for the big prize and target primarily the mass market? Thanks for your input

• Facebook og:url ignored in favour of a Facebook hosted page about the og entity

  - by Dan

  I am trying to implement the Like button on my pages. Those pages represent the review page for a product. When a user Likes the page, it shows up in Facebook (not as a link, but as liking an entity), however when you click on the entity in Facebook it links through to a facebook.com hosted page representing the page. I want the user to be redirected to the og:url page? This happens for example when you Like an artist page on Grroveshar: http://grooveshark.com/#!/artist/Elbow/4795 I am clearly "doing it wrong". I am using the following markup to include the SDK. MYAPPID is included by the code generator Facebook provides so I assume it is required. <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId=MYAPPID"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> Then my code to render the Like button. <div class="fb-like" data-send="false" data-width="450" data-show-faces="true"></div> And finally my og tags: <meta property="og:title" content="My product" /> <meta property="og:type" content="product" /> <meta property="og:url" content="http://site.com/product_1/" /> <meta property="og:image" content="http://site.com/image1.jpg" /> <meta property="og:site_name" content="My-Site-Name.com" /> <meta property="fb:admins" content="MYFACEBOOKID" /> <meta property="fb:app_id" content="MYAPPID" /> Thanks!

• Building a custom (dynamic) dataset and grid

  - by marko.ivanovski.nz

  Hi, I'm in the process of building a dynamic table in which you can add/remove rows & columns so it varies in size depending on what the user wants. Its purpose is to store properties for a product, but there can be from 1 to 10 different properties(columns) per product, and multiple instances(rows) of the product as well. Here's a screenshot of what I mean http://i40.tinypic.com/nbqkxc.jpg As you can see I need the structure to be completely up to the client which is where I'm getting stuck. I've started writing a custom DataSet that has "add column" & "add row" buttons, and have built a custom Table with Textboxes in each cell which builds from that dataset. I have no idea how to store the data on submit though, and to make it even more complex I need to store this in the database as a string which I think I can do by converting it to XML. Any help is appreciated, I think I just need a pointer in the right direction and am happy to do research from there. Thanks in advance. Marko

• SEO redirects for removed pages

  - by adam

  Hi, Apologies if SO is not the right place for this, but there are 700+ other SEO questions on here. I'm a senior developer for a travel site with 12k+ pages. We completely redeveloped the site and relaunched in January, and with the volatile nature of travel, there are many pages which are no longer on the site. Examples: /destinations/africa/senegal.aspx /destinations/africa/features.aspx Of course, we have a 404 page in place (and it's a hard 404 page rather than a 30x redirect to a 404). Our SEO advisor has asked us to 30x redirect all our 404 pages (as found in Webmaster Tools), his argument being that 404's are damaging to our pagerank. He'd want us to redirect our Senegal and features pages above to the Africa page (which doesn't contain the content previously found on Senegal.aspx or features.aspx). An equivalent for SO would be taking a url for a removed question and redirecting it to /questions rather than showing a 404 'Question/Page not found'. My argument is that, as these pages are no longer on the site, 404 is the correct status to return. I'd also argue that redirecting these to less relevant pages could damage our SEO (due to duplicate content perhaps)? It's also very time consuming redirecting all 404's when our site takes some content from our in-house system, which adds/removes content at will. Thanks for any advice, Adam

• Grouping a list of of entities which has a sublist in c#

  - by mikei

  I have a set of Entities which basically has this structure. {Stats Name="<Product name> (en)" TotalResources="10" ..} {DayStats Date="2009-12-10" TotalResources="5"} {DayStats Date="2009-12-11" TotalResources="5"} {Stats} {Stats Name="<Product name> (us)" TotalResources="10" ..} {DayStats Date="2009-12-10" TotalResources="5"} {DayStats Date="2009-12-11" TotalResources="5"} {Stats} ... What I wan't to extract from this set is a new set entities (or entity in the example above) where the first level has been grouped by the (ignoring the country label) where all/some of the properties has been summmed together, including the the sublist of {DayStas} on a per day basis. So the result set of the example would look something like this: {Stats Name="<Product name>" TotalResources="20" ..} {DayStats Date="2009-12-10" TotalResources="10"} {DayStats Date="2009-12-11" TotalResources="10"} {Stats} ... So my question is: Is it possible to do this in a more elegant way in LINQ rather than the vanilla "loop-trhough-each-entity-and-compare"-way? And I wan't the set to contain the same type of entities as the original set ({Stats}, {DayStats}), your answer doesn't need to include code for that, I can probably work that out by myself. Just letting you know incase you need to take that into account. (I'm sorry if this question has been discussed before, I tried searching to no avail. I guess my searching skills are fuubar ;)) Merry christmas =)

• Single developer, project organization

  - by poke

  I am looking for a good (and free) way to organize some of my personal projects. I am saying "organize" because I'm not sure, if the standard project management software solutions are exactly what I am looking for and especially something what I, as a single developer, need. In general, I just want to keep my progress of my projects organized in some way. I would like to be able to keep track of milestones and split those into multiple smaller tasks, so I can keep track of my progress. So some task/issue based system would probably be good, especially as I also want to keep track of issues/bugs with specific versions (although I alone will create those issues). I am and will be the only developer on those projects, so it doesn't matter if the software is offline or online, and I also don't need any collaboration features (like commenting on things, or assigning tasks to other developers etc). But if there is a good software that fits my needs, and in addition it has those things, I don't really care. After all it's easy enough to not use available features. Many online solutions also offer integrated code hosting. I am using git internally, but I don't plan to push any of the code, so such a feature is not needed either. In case of online solutions however I would like the projects to be closed to the public (some of the online utilities only offer open source projects for free and require payments for private projects). I have looked at some project management solutions already, I also read some similar questions here on SO. But given that I'm a single developer, my focus is probably a bit different as when others ask for a huge distributed software that supports many developers and different collaboration features. Some standard answers such as Trac (which also only supports one project), Redmine and FogBUGZ look interesting, but are a bit off my interest (although you may change my mind on that :P). Currently, I'm looking at Indefero which doesn't look too bad. But what do you think?

• Undefined method `add' on a cucumber step that usually works.

  - by Josiah Kiehl

  I have a path defined: when /the admin home\s?page/ "/admin/" I have scenario that is passing: Scenario: Let admins see the admin homepage Given "pojo" is logged in And "pojo" is an "admin" And I am on the admin home page Then I should see "Hi there." And I have a scenario that is failing: Scenario: Review flagged photo Given "pojo" is logged in And "pojo" is an "admin" ...bunch of steps that create stuff in the database... And I am on the admin home page Then ... the rest of the steps The step that fails in the second one is "And I am on the admin home page" which passes just fine in the first scenario. Here's the error I get: And I am on the admin home page # features/step_definitions/web_steps.rb:18 undefined method `add' for {}:Hash (NoMethodError) ./app/controllers/admin_controller.rb:13:in `index' ./app/controllers/admin_controller.rb:11:in `each' ./app/controllers/admin_controller.rb:11:in `index' /usr/lib/ruby/1.8/benchmark.rb:308:in `realtime' ./features/step_definitions/web_steps.rb:19:in `/^(?:|I )am on (.+)$/' features/admin.feature:52:in `And I am on the admin home page' This is very odd... why would it be fine in the first case, and not in the second where the only difference are a bunch of steps that create records in the db? [edit] Here's the add stuff to database step: Given /^there is a "([^\"]*)" with the following:$/ do |model, table| model.constantize.create!(table.rows_hash) end

• SQL: How do I INSERT primary key values from two tables INTO a master table.

  - by Stefan

  Hello, I would appreciate some help with an SQL statement I really can't get my head around. What I want to do is fairly simple, I need to take the values from two different tables and copy them into an master table when a new row is inserted into one of the two tables. The problem is perhaps best explained like this: I have three tables, productcategories, regioncategories and mastertable. --------------------------- TABLE: PRODUCTCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: BOOKS | Books --------------------------- --------------------------- TABLE: REGIONCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: EU | European Union --------------------------- --------------------------- TABLE: MASTERTABLE --------------------------- COLUMNS: REGION | PRODUCT --------------------------- VALUES: EU | BOOKS --------------------------- I want the values to be inserted like this when a new row is created in either productcategories or regioncategories. New row is created. --------------------------- TABLE: PRODUCTCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: BOOKS | Books --------------------------- VALUES: DVD | DVDs --------------------------- And a SQL statement copies the new values into the mastertable. --------------------------- TABLE: MASTERTABLE --------------------------- COLUMNS: REGION | PRODUCT --------------------------- VALUES: EU | BOOKS --------------------------- VALUES: EU | DVD --------------------------- The same goes if a row is created in the regioncategories. New row. --------------------------- TABLE: REGIONCATEGORIES --------------------------- COLUMNS: CODE | DESCRIPTION --------------------------- VALUES: EU | European Union --------------------------- VALUES: US | United States --------------------------- Copied to the mastertable. --------------------------- TABLE: MASTERTABLE --------------------------- COLUMNS: REGION | PRODUCT --------------------------- VALUES: EU | BOOKS --------------------------- VALUES: EU | DVD --------------------------- VALUES: US | BOOKS --------------------------- VALUES: US | DVD --------------------------- I hope it makes sense. Thanks, Stefan
