  • Drupal Views Duplicate values being returned when using a relationship

    - by Linda
    I am having a problem with views. I have a view and am passing it a taxonomy term by name to it. I then have a relationship to a related node. For my output fields I am returning the related Title and related Body. I however have duplicates in my results. I have turned distinct to yes but believe this is working on the nodes being return and not the related node. Any ideas how I can remove the duplicates? Update Below is the query being run when I only get the title SELECT DISTINCT(node.nid) AS nid, node_node_data_field_wine_company.title AS node_node_data_field_wine_company_title, node_node_data_field_wine_company.nid AS node_node_data_field_wine_company_nid FROM node node LEFT JOIN content_type_wine node_data_field_wine_company ON node.vid = node_data_field_wine_company.vid INNER JOIN node node_node_data_field_wine_company ON node_data_field_wine_company.field_wine_company_nid = node_node_data_field_wine_company.nid LEFT JOIN term_node term_node ON node.vid = term_node.vid INNER JOIN term_data term_data ON term_node.tid = term_data.tid WHERE term_data.name = 'test' GROUP BY nid It looks like I should be grouping by node_node_data_field_wine_company_nid or selecting distinct values from there. Any ideas?

  • Submit HTML form with GET method with full action path

    - by Manny Calavera
    Hello. I am trying to submit a form with method GET and action "index.php?id=3". The problem is that it jumps to the url specified but it cuts off "?id=3" part. I need that so I can identify an user. Any ideas on how I could submit the whole url ? I don't want to change this method, by design is much complex than I told you here. It's a simple version. Any ideas ? Thanks.

  • Modeling distribution of performance measurements

    - by peterchen
    How would you mathematically model the distribution of repeated real life performance measurements - "Real life" meaning you are not just looping over the code in question, but it is just a short snippet within a large application running in a typical user scenario? My experience shows that you usually have a peak around the average execution time that can be modeled adequately with a Gaussian distribution. In addition, there's a "long tail" containing outliers - often with a multiple of the average time. (The behavior is understandable considering the factors contributing to first execution penalty). My goal is to model aggregate values that reasonably reflect this, and can be calculated from aggregate values (like for the Gaussian, calculate mu and sigma from N, sum of values and sum of squares). In other terms, number of repetitions is unlimited, but memory and calculation requirements should be minimized. A normal Gaussian distribution can't model the long tail appropriately and will have the average biased strongly even by a very small percentage of outliers. I am looking for ideas, especially if this has been attempted/analysed before. I've checked various distributions models, and I think I could work out something, but my statistics is rusty and I might end up with an overblown solution. Oh, a complete shrink-wrapped solution would be fine, too ;) Other aspects / ideas: Sometimes you get "two humps" distributions, which would be acceptable in my scenario with a single mu/sigma covering both, but ideally would be identified separately. Extrapolating this, another approach would be a "floating probability density calculation" that uses only a limited buffer and adjusts automatically to the range (due to the long tail, bins may not be spaced evenly) - haven't found anything, but with some assumptions about the distribution it should be possible in principle. Why (since it was asked) - For a complex process we need to make guarantees such as "only 0.1% of runs exceed a limit of 3 seconds, and the average processing time is 2.8 seconds". The performance of an isolated piece of code can be very different from a normal run-time environment involving varying levels of disk and network access, background services, scheduled events that occur within a day, etc. This can be solved trivially by accumulating all data. However, to accumulate this data in production, the data produced needs to be limited. For analysis of isolated pieces of code, a gaussian deviation plus first run penalty is ok. That doesn't work anymore for the distributions found above. [edit] I've already got very good answers (and finally - maybe - some time to work on this). I'm starting a bounty to look for more input / ideas.

  • Displaying Django Messages Framework Messages

    - by Arif
    I have been using the Django Messaging Framework to display messages to a user in the template. I am outputting them to the template like this: <ul> {% for message in messages %} <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li> {% endfor %} </ul> This outputs all the messages, errors, warning, success etc. I was just wondering if anyone had any ideas how to display only the error messages something like: <ul> {% for message in messages.errors %} <li>{{ message }}</li> {% endfor %} </ul> Any ideas? Thanks in advance.

  • NSStatusItem (cocoa) location on screen

    - by Craig
    I am trying to get the on screen location of an NSStatusItem so that I can perform a click on that area via code like below. I am doing this so that my users can press a hotkey to see the menu. event = CGEventCreateMouseEvent(NULL, kCGEventLeftMouseDown, newLocation, kCGMouseButtonLeft); CGEventPost(kCGHIDEventTap, event); CFRelease(event); Does anyone know of a way to get the location?, I have been trying ideas and searching for days and have found several ideas but none of them seem to work in leopard/snow leopard The NSStatusItem is using an NSMenu not a custom view.

  • Distributing points over a surface within boundries

    - by vise
    I'm interested in a way (algorithm) of distributing a predefined number of points over a 4 sided surface like a square. The main issue is that each point has got to have a minimum and maximum proximity to each other (random between two predefined values). Basically the distance of any two points should not be closer than let's say 2, and a further than 3. My code will be implemented in ruby (the points are locations, the surface is a map), but any ideas or snippets are definitely welcomed as all my ideas include a fair amount of brute force.

  • Unable to remove master -> child subform links in microsoft access 2003

    - by Doug
    Hi, I am having an issue removing the master - child link fields in an access subreport data form. I have tried every avenue to remove them, using the properties window of the subreport as well as the link wizard. I have also deleted the subreport from the database and then gone as far as re-importing the existing objects into a new access instance. As soon as I re-added the subform back in and name it the same name the link fields show back up. Something is apparently corrupt, but I have run out of ideas at this point on how to clear them. Any Ideas would be appreciated. Thanks Doug

  • Keeping files or database records? Java and Python

    - by danpalmer
    My website will use a Neural Network to predict thing based on user data. The user can select the data to be used in training the network and then use their trained network to predict things. I am using a framework to create, train and query the networks. This uses Java. The framework has persistence for saving a network to an XML file. What is the best way to store these files? I can see several potential ideas, but I need help on choosing which is best: Save each network to a separate XML file with a name that is stored in the database. Load this each time. Save all the networks to the same XML file with each network having a different name that is stored in the database. Somehow pass what would normally be written to an XML file to the Django site for writing to the database. This would need to be returned to the Java code when a prediction needs to be made. I am able to do 1 or 2, but I think their performance will be quite limited and I am on shared hosting at the moment, so I don't know how pleased they would be with thousands of files. Also, after adding a few thousand records to one XML file, I was noticing a massive performance hit on saving to it. If I were able to implement version 3 somehow I think it would be best. No issues with separate processes accessing the database and I think performance would be better. Not to mention having no files lying around. However, the stuff in the neural network framework I am using (Encog) for saving to a file needs access to a Java file object, not a string that could be saved to a database. Unless there is some Java magic I can do here (I know very little Java), the only way I can see of doing this would be with a temporary files but I don't know if this is the correct way to do it. I would appreciate any ideas on the best way to implement any of the above 3 ideas or any alternatives. Thanks!

  • Providing dynamic data to webpage

    - by Marius
    Hi, I have a web page that displays dynamic data which changes every 2 seconds. Data is selected from various data sources including Oracle. Currently, the page reloads every 10 seconds and runs a PHP script which retrieves the data and displays the page. I have other pages that gives a different view on the same data. This means the same query is run again for them as well. If I have 4 of these pages with 10 concurrent users each, suddenly the data retrieval happens 40 times every 10 seconds, obviously not ideal. I have some ideas on how to improve this situation, but I thought I would ask from some ideas from other experts that might have come across a similar situation. I'm not bound to PHP, and my server is on a Linux platform. Regards Marius

  • Self Assessment Tests for Programmers

    - by THX1138.6
    I want to help the Dev team identify areas of knowledge (practical and theoretical) that they can work on. Though I am big believer in focusing on people's strengths being a good programmer requires (I think) being challenged by concepts and ideas that don't always come naturally. We work largely in the web app space using PHP & MySQL but better skills in data modelling, query optimisation, use of MVC and OOP etc. would help the team and the company a lot. I want to help the Dev team manage their careers, explore and expand their skills sets. Be all they can be and better than they were previously. I know its an idealistic goal but work must be about more than simply getting the work done. There should be some time to review, to learn, to grow and get better. Any thoughts, ideas, opinions and directions to tests or similar resources would be greatly appreciated.

  • Need Help on a custom HTML Helper

    - by LeeHull
    I'm trying to create a custom HTML Helper to help simplify my masterpages menu, however it is not rendering on the HTML when I use it.. I'm thinking I will need to create a partial view, any ideas? I did this.. public static string CreateAdminMenuLink(this HtmlHelper helper, string caption, string link) { var lnk = TagBuilder("a"); lnk.SetInnerText(caption); lnk.MergeAttribute("href", target); return lnk.ToString(TagRenderMode.SelfClosing); } Now in my View, i have <% Html.CreateAdminMenuLink("Home", "~/Page/Home"); %> but when I look at the source, its empty.. tried adding <% using (Html.BeginForm()) % and it adds a form.. but the link still doesnt come up.. debugged and the string works when i look at the watch, but does not render.. Any ideas?

  • Removing all CALayer's sublayers

    - by radex
    Hi. I have trouble with deleting all layer's sublayers. I do this manually, but it's unwanted code clutter. I found many topics about this in google, but no answer. I tried to do something like this: for(CALayer *layer in rootLayer.sublayers) { [layer removeFromSublayer]; } but it didn't work. Also, i tried to clone rootLayer.sublayers into separate NSArray, but result was the same. Any ideas? regards, radex PS. sorry for my English. Edit: I thought it works now, but I was wrong. It works good with CALayers, but it doesn't work with CATextLayers. Any ideas?

  • Mixin or Trait implementation in AS3?

    - by Brian Heylin
    I'm looking for ideas on how to implement a Mixin/Trait style system in AS3. I want to be able to compose a number of classes together into a single object. Of course this is not a language level feature of AS3, but I'm hoping that there is maybe some way to do this using prototype based techniques or maybe some bytecode hacking that I believe AsMock uses to implement it's functionality. An existing Java example is Qi4J where the user define interfaces that the Qi4j framework implements based on metadata tags and coding by convention. Has anyone any ideas on how to get the Mixin/Trait concept working within AS3?
