• Simple rails routing / url question

  - by justinbach

  I'm using Ryan Bates' nifty authentication in my application for user signup and login. Each user has_many :widgets, but I'd like to allow users to browse other users' widgets. I'm thinking that a url scheme like /username/widgets/widget_id would make a lot of sense--it would keep all widget-related code in the same place (the widgets controller). However, I'm not sure how to use this style of URL in my app. Right now my codebase is such that it permits logged-in users to browse only their own widgets, which live at /widgets/widget_id. What changes would I need to make to routes.rb, my models classes, and any place where links to a given widget are needed? I've done Rails work before but am a newb when it comes to more complicated routing, etc, so I'd appreciate any feedback. Thanks for your consideration!

• Rails routing: how to mix "GET" and "PUT"

  - by thermans

  Not sure how to frame this question (I'm still wrapping my head around Rails). Let's try this: Say I wanted to implement the user side of Ryan Bates' excellent railscast on nested models. (He shows how to implement a survey where you can add and remove questions and answers dynamically). I want the user's side of this: to be able to answer questions and, not in the tutorial, be able to add comments. It seems to me that you have to implement a view that shows the questions and answers, allow selection of the answers, and the input of comments. So there would need to be a way to show the information, but also update the model on input, right? I know I'm not explaining this very well. I hope you understand what I'm getting at. Is it just a question of setting up the right routes? Or is there some controller mojo that needs to happen?

• Creating WebService test harness

  - by user232337

  Hello, I am trying to create a test harness for our QA staff to test our internal web services. I would like to create a web app that will allow them to enter a uri then submit. The web app will then interrogate the uri to get the appropriate parameters expected and returns with a generated input form. I know, this would be similar to SOAPUI and others. However, I feel it would be earier for them to be able to just use a form with entry fields and click a button to invoke the service and get the results back for display in the web app. In addition, I could create some custom logic that allows them to generate specific behavior they need. Has anybody done anything like this? I have searched and have found similar functionality but nothing close enough to help me. If you need more details please let me know. Any help would be greatly appreciated. Thanks in advance! Ryan

• How do I quiet image_submit_tag from params hash?

  - by Alan S

  Does anyone know how to eliminate the x and y params when you use image_submit_tag with a get method? I have a simple search form, and using get to pass the value in the url. When I use image_submit_tag, it also appends the x and y coords, so I get urls like http://example.com?q=somesearchterm&x=15&y=12 When I have used submit_tag, I can use the :name = nil attribute (was in one of Ryan Bates' Railscasts), but it doesn't seem to work for image_submit_tag. Granted it doesn't affect functionality, but I don't need them and would like them quieted.

• Why does using set -e cause my script to fail when called in crontab

  - by SDGuero

  I have a bash script that performs several file operations. When any user runs this script, it executes successfully and outputs a few lines of text but when I try to cron it there are problems. It seems to run (I see an entry in cron log showing it was kicked off) but nothing happens, it doesn't output anything and doesn't do any of its file operations. It also doesn't appear in the running processes anywhere so it appears to be exiting out immediately. After some troubleshooting I found that removing "set -e" resolved the issue, it now runs from the system cron without a problem. So it works, but I'd rather have set -e enabled so the script exits if there is an error. Does anyone know why "set -e" is causing my script to exit? Thanks for the help, Ryan

• ExtJS: Ext.data.DataReader: #realize was called with invalid remote-data

  - by TomH

  I'm receiving a "Ext.data.DataReader: #realize was called with invalid remote-data" error when I create a new record via a POST request. Although similar to the discussion at this SO conversation, my situation is slightly different: My server returns the pk of the new record and additional information that is to be associated with the new record in the grid. My server returns the following: {'success':true,'message':'Created Quote','data': [{'id':'610'}, {'quoteNumber':'1'}]} Where id is the PK for the record in the mysql database. quoteNumber is a db generated value that needs to be added to the created record. Other relevant bits: var quoteRecord = Ext.data.Record.create([{name:'id', type:'int'},{name:'quoteNumber', type:'int'},{name:'slideID'}, {name:'speaker'},{name:'quote'}, {name:'metadataID'}, {name:'priorityID'}]); var quoteWriter = new Ext.data.JsonWriter({ writeAllFields:false, encode:true }); var quoteReader = new Ext.data.JsonReader({id:'id', root:'data',totalProperty: 'totalitems', successProperty: 'success',messageProperty: 'message',idProperty:'id'}, quoteRecord); I'm stumped. Anyone?? thanks tom

• Creating meaningful add URLs in Cakephp

  - by Loftx

  Hi there, For my site I have a number of Orders each of which contains a number of Quotes. A quote is always tied to an individual order, so in the quotes controller I add a quote with reference to it's order: function add($orderId) { // funtion here } And the calling URL looks a bit like http://www.example.com/quotes/add/1 It occurred to me the URLs would make more sense if they looked a bit more like http://www.example.com/orders/1/quotes/add As the quote is being added to order 1. Is this something it's possible to achive in CakePHP? Cheers, Tom

• Repeater and add columns to header and itemtemplate on page load

  - by sdmiller

  I haven't used repeaters for much more than showing data from a datatable. I am building a grid that that shows a list of users and columns of roles that the user has been assigned, shown with checkboxes (shown with true/false below but pretent they are checkboxes). ex. |Rep Name|Caller|Closer|Manager|SuperUser| |Bob |True |true | false | false | |Tom |false |false |True | True | Basically using it for roles management. However the roles may change later on so I want to load the roles(headers and items) dynamically into the repeater. I am not sure how to do this or if it is even possible. I figure you grab a list of current role possibilities and load them into the headertemplate but I am not sure how to match those with the itemtemplate and how to create checkboxes and place them in the itemtemplate. Sorry if it is a rudementary question.... I appreciate any advice!

• Unknown Apache2 + PHP5 FastCGI 500 error .. caused by search engine bots?

  - by rdjurovich

  My Ubuntu server is configured with Apache 2.2.8 and PHP 5.2.4-2ubuntu5.18 in FastCGI mode. Everything works well, except I am seeing 500 errors that only seem to come from bots accessing the server.. for example (access.log): x.125.71.104 - - [16/Nov/2011:10:27:39 +1100] "GET / HTTP/1.1" 500 41377 "-" "Mozilla/5.0 (compatible; Baiduspider/2.0; +http://www.baidu.com/search/spider.html)" x.40.103.239 - - [16/Nov/2011:11:05:56 +1100] "GET / HTTP/1.0" 500 14717 "-" "Mozilla/5.0 (compatible; mon.itor.us - free monitoring service; http://mon.itor.us)" x.249.67.114 - - [14/Nov/2011:20:57:17 +1100] "GET / HTTP/1.1" 500 101 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" x.55.39.85 - - [14/Nov/2011:19:31:06 +1100] "GET / HTTP/1.1" 500 7032 "-" "msnbot/2.0b (+http://search.msn.com/msnbot.htm)._" It is my understanding that a 500 error will be thrown when the PHP process fails to respond to Apache, which could be caused by a fatal PHP error or if PHP runs out of processes.. so my assumption is that either the bots are hitting the server too hard, killing the PHP processes, or something in the request header from bots is causing a fatal error in my PHP script? If anyone can offer advice on this it would be greatly appreciated! Ryan

• Using Solr and Zends Lucene port together...

  - by thebluefox

  Afternoon chaps, After my adventures with Zend-Lucene-Search, and discovering it isn't all its cracked up to be when indexing large datasets, I've turned to Solr (thanks to Bill Karwin for that :) ) I've got Solr indexing the db far far quicker now, taking just over 8 minutes to index a table of just over 1.7million rows - which I'm very pleased with. However, when I come to try and search the index with the Zend port, I run into the following error; Fatal error: Uncaught exception 'Zend_Search_Lucene_Exception' with message 'Unsupported segments file format' in /var/www/Zend/Search/Lucene.php:407 Stack trace: #0 /var/www/Zend/Search/Lucene.php(555): Zend_Search_Lucene-_readSegmentsFile() #1 /var/www/z_search.php(12): Zend_Search_Lucene-__construct('tmp/feeds_index') #2 {main} thrown in /var/www/Zend/Search/Lucene.php on line 407 I've tried to have a search around but can't seem to find anything about this problem, everyone just seems to be able to get them to work? Any help as always much appreciated :) Thanks, Tom

• Add comma-separated value of grouped rows to existing query

  - by Peter Lang

  I've got a view for reports, that looks something like this: SELECT a.id, a.value1, a.value2, b.value1, /* (+50 more such columns)*/ FROM a JOIN b ON (b.id = a.b_id) JOIN c ON (c.id = b.c_id) LEFT JOIN d ON (d.id = b.d_id) LEFT JOIN e ON (e.id = d.e_id) /* (+10 more inner/left joins) */ It joins quite a few tables and returns lots of columns, but indexes are in place and performance is fine. Now I want to add another column to the result, showing comma-separated values ordered by value from table y outer joined via intersection table x if a.value3 IS NULL, else take a.value3 To comma-separate the grouped values I use Tom Kyte's stragg, could use COLLECT later. Pseudo-code for the SELECT would look like that: SELECT xx.id, COALESCE( a.value3, stragg( xx.val ) ) value3 FROM ( SELECT x.id, y.val FROM x WHERE x.a_id = a.id JOIN y ON ( y.id = x.y_id ) ORDER BY y.val ASC ) xx GROUP BY xx.id What is the best way to do it? Any tips?

• Trying to speed up a SQLITE UNION QUERY

  - by user142683

  I have the below SQLITE code SELECT x.t, CASE WHEN S.Status='A' AND M.Nomorebets=0 THEN S.PriceText ELSE '-' END AS Show_Price FROM sb_Market M LEFT OUTER JOIN (select 2010 t union select 2020 t union select 2030 t union select 2040 t union select 2050 t union select 2060 t union select 2070 t ) as x LEFT OUTER JOIN sb_Selection S ON S.MeetingId=M.MeetingId AND S.EventId=M.EventId AND S.MarketId=M.MarketId AND x.t=S.team WHERE M.meetingid=8051 AND M.eventid=3 AND M.Name='Correct Score' With the current interface restrictions, I have to use the above code to ensure that if one selection is missing, that a '-' appears. Some feed would be something like the following SelectionId Name Team Status PriceText =================================== 1 Barney 2010 A 10 2 Jim 2020 A 5 3 Matt 2030 A 6 4 John 2040 A 8 5 Paul 2050 A 15/2 6 Frank 2060 S 10/11 7 Tom 2070 A 15 Is using the above SQL code the quickest & efficient?? Please advise of anything that could help. Messages with updates would be preferable.

• Connecting to SQL Server with Visual Studio Express Editions

  - by tlianza

  I find it odd that in Visual C# 2008 Express edition, when you use the database explorer, your options are: 1) Microsoft Access 2) SQL Server Compact 3.5, and 3) SQL Server Database File. BUT if you use Visual Web Developer 2008 Express, you can connect to a regular SQL Server, Oracle, ODBC, etc. For people developing command-line or other C# apps that need to talk to a SQL Server database, do you really need to build your LINQ/Data Access code with one IDE (Visual Web Developer) and your program in another (Visual C#)? It's not a hard workaround, but it seems weird. If Microsoft wanted to force you to upgrade to Visual Studio to connect to SQL Server, why would they include that feature in one of their free IDEs but not the other? I feel like I might be missing something (like how to do it all in Visual C#). Thanks! Tom

• Regex Pattern for ignoring a custom escape character

  - by user1517464

  I am trying to find a suitable regex for matching pair of custom characters in an input string. These custom characters are replaced by their corresponding html tags. For e.g. The input string can have underscores in pairs to indicate words in bold. Hence, _Name_ outputs as <b>Name</b> However if there is a genuine underscore in the string, it cannot be replaced by "bold" tags and has to be ignored. The genuine underscore has to be preceded by / (I couldn't find a better character, it could be one more underscore or hyphen or whatever). Any single or paired occurrance of this genuine underscore has to be ignored by regex. So far I could come up with this regex: var pattern = @"(?!/)_(.*?)(?!/)_"; But it fails in below input string: _Tom_Katy/_Richard/_/_Stephan_and many users It outputs as <b>Tom</b>Katy/<b>Richard/_/</b>Stephan_and many users Many Thanks in Advance, Pr

• 301 Redirects, and the correct regex to go with it

  - by Tisch

  Hi Guys, I have several URLs that I want to redirect to the same place, however these are dynamic URLs. The structure is something like this: http://www.mysite.com/declaration/list?[query_string] What I think would be ideal for this situation is to use some regex in my .htaccess file to redirect all these links to the sites home page. I was wondering if someone could help me with the regex for this situation. So far, I have this, but it doesn't work: RewriteCond %{QUERY_STRING} ^(.*)$ RewriteRule ^/declaration/list$ http://www.mysite.com/$ [R=301,L] My regex is weak to say the least, something I want to, and am trying to learn. Thanks in advance. Tom

• What are appropriate ways to represent relationships between people in a database table?

  - by Emilio

  I've got a table of people - an ID primary key and a name. In my application, people can have 0 or more real-world relationships with other people, so Jack might "work for" Jane and Tom might "replace" Tony and Bob might "be an employee of" Rob and Bob might also "be married to" Mary. What's the best way to represent this in the database? A many to many intersect table? A series of self joins? A relationship table with one row per relationship pair and type, where I insert records for the relationship in both directions?

• mySQL one-to-many query

  - by Stomped

  I've got 3 tables that are something like this (simplified here ofc): users user_id user_name info info_id user_id rate contacts contact_id user_id contact_data users has a one-to-one relationship with info, although info doesn't always have a related entry. users has a one-to-many relationship with contacts, although contacts doesn't always have related entries. I know I can grab the proper 'users' + 'info' with a left join, is there a way to get all the data I want at once? For example, one returned record might be: user_id: 5 user_name: tom info_id: 1 rate: 25.00 contact_id: 7 contact_data: 555-1212 contact_id: 8 contact_data: 555-1315 contact_id: 9 contact_data: 555-5511 Is this possible with a single query? Or must I use multiple?

• What's the best way to count unique visitors with Hadoop?

  - by beagleguy

  hey all, just getting started on hadoop and curious what the best way in mapreduce would be to count unique visitors if your logfiles looked like this... DATE siteID action username 05-05-2010 siteA pageview jim 05-05-2010 siteB pageview tom 05-05-2010 siteA pageview jim 05-05-2010 siteB pageview bob 05-05-2010 siteA pageview mike and for each site you wanted to find out the unique visitors for each site? I was thinking the mapper would emit siteID \t username and the reducer would keep a set() of the unique usersnames per key and then emit the length of that set. However that would be potentially storing millions of usernames in memory which doesn't seem right. Anyone have a better way? I'm using python streaming by the way thanks
