  • rails restful select_tag with :on_change

    - by Sam
    So I'm finally starting to use rest in rails. I want to have a select_tag with product categories and when one of the categories is selected I want it to update the products on change. I did this before with <% form_for :category, :url => { :action => "show" } do |f| %> <%= select_tag :id, options_from_collection_for_select(Category.find(:all), :id, :name), { :onchange => "this.form.submit();"} %> <% end %> however now it doesn't work because it tries to do the show action. I have two controllers 1) products 2) product_categories products belongs_to product_categories with a has_many How should I do this. Since the products are listed on the products controller and index action should I use the products controller or should I use the product_categories controller to find the category such as in the show action and then render the product/index page. But the real problem I have is how to get this form or any other option to work with restful routes.

  • Wrapping <%= f.check_box %> inside <label>

    - by Ben Scheirman
    I have a list of checkboxes on a form. Due to the way the CSS is structured, the label element is styled directly. This requires me to nest the checkbox inside of the tag. This works in raw HTML, if you click on the label text, the state of the checkbox changes. It doesn't work with the rails <%= f.check_box %> helper, however, because it outputs a hidden input tag first. In summary, <label> <%= f.check_box :foo %> Foo </label> this is the output I want: <label> <input type="checkbox" ... /> <input type="hidden" ... /> Foo </label> ...but this is what rails is giving me: <label> <input type="hidden" ... /> <input type="checkbox" ... /> Foo </label> So the label behavior doesn't actually work :(. Is there any way to get around this?

  • How to stop auto encoding of <%= strings %> with Rails 3.0beta

    - by christophercotton
    I'm using rails 3.0beta3. In my index.html.erb and in my index.js.erb, if I have: <%= "string with unsafe characters' like <" %> It will automatically be encoded to: string with unsafe characters&quot; like &amp; just the same as if I had used: <%=h "string with unsafe characters' like <" %> How do I get it to stop? I have stored some short bits of JavaScript that I need to insert into the template without it automatically encoding the string?

  • Why is my ruby application running faster the second time?

    - by Omega
    I'm creating a Ruby game using the Gosu framework. All good. Sometimes, when I run the game, it has some kind of slow startup, and probably it will be rather slow during the whole game. So I close it and... open it again. It is very likely that it will startup quickly and the whole game will run smoothly and fast. Why is that? What is this phenomenon? Is it faster because of some cache stored or whatever since the first run? (But why would cache be stored? If the app dies, I would expect no references at all etc...) Ruby, Windows 7.

  • export to csv using fastercsv and CSV::Writer (Ruby on Rails)

    - by Venkat
    What am I trying to do: export data to csv. I have a form which allows user to select the format (from a drop down menu). So based on the selection of the format the ouput is displayed using a ajax call. Works fine for html but when I select the format as csv I don't see any pop up on the screen (asking to save or open the file) and neither any file gets downloaded directly. I tried using Fastercsv (but the problem is that I don't see any pop up asking me whether I want to save or open the file) and CSV::Writer where I get this error message on the console. NoMethodError (You have a nil object when you didn't expect it! The error occurred while evaluating nil.bytesize): actionpack (2.3.4) lib/action_controller/streaming.rb:142:in `send_data' Code using Fastercsv: def export_to_csv csv_string = FasterCSV.generate(:col_sep => ",") do |csv| members = ["Versions / Project Members"] members_selected.each {|member| members << Stat.member_name(member)} Stat.project_members(project).each {|user| members << user.name} csv << ["some text", "text 2", "text 3"] end return csv_string end and this is how I am sending the data: send_data(export_to_csv,:type => 'text/csv; charset=iso-8859-1; header=present', :disposition => "attachment", :filename => "filename.csv") I see the response as "some text, text 2, text 3" in the firebug console but no pop up asking whether I want to save or open the file. This is what I am doing using CSV::Writer: def export_to_csv report = StringIO.new CSV::Writer.generate(report, ',') do |csv| csv << ['c1', 'c2'] end end and call it as: send_data(export_to_csv,:type => 'text/csv; charset=iso-8859-1; header=present', :disposition => "attachment", :filename => "filename.csv") This is the error which is thrown on the console: NoMethodError (You have a nil object when you didn't expect it! The error occurred while evaluating nil.bytesize): actionpack (2.3.4) lib/action_controller/streaming.rb:142:in `send_data'

  • error executing aapt, all of the sudden

    - by pjv
    I know there are a lot of these topics around but none seem to help in my case, nor describe it exactly. The best similar one is aapt not found under the right path. My problem is that I can be using Eclipse for a whole evening programming, compiling and using my device, and then suddenly I get "error executing aapt" for my current project and ofcourse R.java isn't (properly) generated anymore. I then restart Eclipse and everything goes away. I'm seeing this once a day on average however. I've recently switched to amd64 and installed the latest Android-2.3 SDK and matching tools. I know that there is now a platform-tools folder that has an aapt version that should work SDK version independently. At first I had added this directory to my PATH, as instructed on the SDK website. I've also tried not adding it to my path and making a link platforms/android-9/tools so that every SDK version might use it's own old copy. Needless to say, platform-tools/aapt is there and has the right permissions, and I have been able to execute it on the command-line at any time. When I do write a faulty xml file or sorts, and appropriately get an error, I see an extra line that says "aapt: /lib32/libz.so.1: no version information available". I'm running a recent Gentoo linux system. I have everything installed to support x86 on amd64, but have re-emerged emul-linux-x86-baselibs and zlib just to be sure. The problem persists. I do see some pages that spell horror over some zlib bugs, but I'm not sure if that's related. I realize I'm not on the reference Ubuntu platform, but surely the difference cannot be that great? It might very well be a bug in aapt or the tools itself. Why would it suddenly stop working? I also experience that the ids in R.java were incorrect, namely that simple findViewById() code would give ClassCastExceptions because of mixed ids the one time, and then work perfectly without any changes bu only a "clean project", in the aftermath of a failing aapt. Finally, I've run a few commands on aapt, that don't seem to add any extra information: #ldd aapt ./aapt: /lib32/libz.so.1: no version information available (required by ./aapt) linux-gate.so.1 => (0xffffe000) librt.so.1 => /lib32/librt.so.1 (0x4f864000) libpthread.so.0 => /lib32/libpthread.so.0 (0x4f849000) libz.so.1 => /lib32/libz.so.1 (0xf7707000) libstdc++.so.6 => /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.4/32/libstdc++.so.6 (0x415e9000) libm.so.6 => /lib32/libm.so.6 (0x4f876000) libgcc_s.so.1 => /lib32/libgcc_s.so.1 (0x4fac6000) libc.so.6 => /lib32/libc.so.6 (0x4f5ed000) /lib/ld-linux.so.2 (0x4f5ca000) #file aapt aapt: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.15, not stripped Can anybody tell anything wrong with my configuration? Does it smell like a bug perhaps (otherwise let's report it (again))? Update 2010-01-06: I've gained some more knowledge. When I recently was trying to export a signed apk, I ran into another error message (full details from the Eclipse error view) regarding aapt I hadn't seen before. Note here too, that I can just restart Eclipse and can export apks again without problems, at least for a little while. I'm starting to think it is related to lack of memory on my system. The message "onvoldoende geheugen beschikbaar" means "insufficient memory available". I have also been seeing insufficient memory errors in DDMS when I'm dumping HPROF files. Here is the error log (shortened): !ENTRY com.android.ide.eclipse.adt 4 0 2011-01-05 23:11:16.097 !MESSAGE Export Wizard Error !STACK 1 org.eclipse.core.runtime.CoreException: Failed to export application at com.android.ide.eclipse.adt.internal.project.ExportHelper.exportReleaseApk(Unknown Source) at com.android.ide.eclipse.adt.internal.wizards.export.ExportWizard.doExport(Unknown Source) at com.android.ide.eclipse.adt.internal.wizards.export.ExportWizard.access$0(Unknown Source) at com.android.ide.eclipse.adt.internal.wizards.export.ExportWizard$1.run(Unknown Source) at org.eclipse.jface.operation.ModalContext$ModalContextThread.run(ModalContext.java:121) Caused by: com.android.ide.eclipse.adt.internal.build.AaptExecException: Error executing aapt.

  • How can I make Ruby rake display the full backtrace on uncaught exception

    - by Martinos
    As you may know rake swallows the full backtrace on uncaught exception. If I want to have a full backtrace, I need to add the --trace option. I find this very annoying because some of my tasks take long time to run (up to 6 hours), when it crashes I don't have any debugging info. I need to run it again with the --trace. On top of that, the system may not be in the same state as when the error occurred, so it may not show afterward. I always have to add --trace on any tasks. This displasy stuff that I don't want to see when the task is executed. Is there a way to change this default behaviour? (which I don't think is useful at all)

  • Can I change from BIOS IDE mode to AHCI mode at any time?

    - by Software Monkey
    Currently my Windows 7 computer is crashing during startup, after loading the AMD achix64s.sys driver, if I enable BIOS AHCI mode for the disks. It boots fine with IDE mode. Since I need my computer working, I am wondering if I can just use IDE mode for now, and later change to AHCI mode, when I figure out what is wrong. Background: I was running RAID mode, which needed additional drivers to install/boot Windows. But the MoBo RAID is flaky so I'm trying to switch to using a Windows mirrored volume instead - for that I expected to use AHCI mode.

  • Ruby on Rails AJAX call affects only the first element in collection

    - by pruett
    I'm iterating over a collection of elements and trying to get AJAX to work properly on a specific element within the collection. I'm nesting a few partials in order to iterate over these items and use a js.erb call like this: $('#favorite_form').html("<%=j render partial: 'shared/unfavorite', locals: { mission: @mission } %>"); This only seems to change the 1st item in the collection even though I could be clicking the 5th item down the list, for example. Question: How can I specify (via .js and AJAX) which element to update? Is this jQuery call not specific enough to the individual element? The code works in regular HTTP requests, so I'm wondering if there is a way to specify the individual element, but I thought that's what partials did :/ Example View ( _favorites.html.erb ) <div id="favorite_form"> <% if you_favorited_this?(current_user, mission) %> <%= render partial: 'shared/unfavorite', locals: { mission: mission } %> <% else %> <%= render partial: 'shared/favorite', locals: { mission: mission } %> <% end %> </div>

  • Nokogiri (Ruby) and XPath

    - by JP
    Does Nokogiri only support XPath 1.0? I'm trying to do simple string replacement in a value-of cell, like so (where element contains something like '* My string (useless text)') <xsl:value-of select="replace(element,'^\*\ (.+)\ \(.*\)$','\\1')"> Is this poorly formed XSL? Or is there a limitation with Nokogiri?
