  • Rails: How to name and create unique divs within a loop?

    - by sscirrus
    I have a view with a div that is looped many times. Each of the created divs need to have a unique ID so I can access them specifically (at the moment, all my divs have the same ID specified in html so whenever I try to access a specific div it just finds the first one). This is the version that I currently have (multiple 'rowBox'es are not discernible). <% @customers.each do |customer| %> <div id="customer" class="rowBox"> ... </div> <% end %> I would like to be able to do something like: <% @customers.each do |customer| %> <div id="box<%=customer.id%>"> ... </div> <% end %> This doesn't seem to work. Any ideas on how to accomplish this?

  • Saving an ActiveRecord non-transactionally.

    - by theFunkyEngineer
    My application accepts file uploads, with some metadata being stored in the DB, and the file itself on the file system. I am trying to make the metadata visible in the application before the file upload and post-processing are finished, but because saves are transactional, I have had no success. I have tried the callbacks and calling create_or_update() instead of save(), all to no avail. Is there a way to do this without re-writing the guts of ActiveRecord::Base? I've even attempted naming the method make() instead of save(), but perplexingly that had no effect. The code below "works" fine, but the database is not modified until everything else is finished. def save(upload) uploadFile = upload['datafile'] originalName = uploadFile.original_filename self.fileType = File.extname(originalName) create_or_update() # write the file File.open(self.filePath, "wb") { |f| f.write(uploadFile.read) } begin musicFile = TagLib::File.new(self.filePath()) self.id3Title = musicFile.title self.id3Artist = musicFile.artist self.id3Length = musicFile.length rescue TagLib::BadFile => exc logger.error("Failed to id track: \n #{exc}") end if(self.fileType == '.mp3') convertToOGG(); end create_or_update() end Any ideas would be quite welcome, thanks.

  • Can you recommend wiki, forum, blog & cms plugins for an existing Rails app or should I go the route

    - by Nick Gorbikoff
    Hello. I have an existing Rails internal app, that handles inventory, invoicing, order taking, labeling, data imports/exports, etc, etc. Now I need to add blog, cms, forum and wiki functionality to it. It seems silly to try to roll out my own solutions when there are already some out there. So I was wondering if people could recommend based on their experience: Are there good plugins out there? (Which ones you had experience with?) Would you rather recommend to go the route of engines, and integrate RadiantCMS or similar apps? (please provide recommendations based on your integration experience) Or would you just bite the bullet and roll out your own? Thank you. P.S.: Right now the app is Rails 2.3, but it will get upgraded to Rail 3 in a year, when most gems/plugins that it depends on will be Rails 3 compatible.

  • Returning a 1x1 .gif as a response in Rails

    - by Avishai
    Hi, I'm building a Rails app that does conversion tracking on outside sites. I'd like to allow users to paste an image tag in their conversion pages (like AdWords), and whenever that image is requested, a conversion registers in my app. respond_to do |format| if @conversion.save flash[:notice] = 'Conversion was successfully created.' format.html { redirect_to(@conversion) } format.xml { render :xml => @conversion, :status => :created, :location => @conversion } format.js { render :json => @conversion, :status => :created } format.gif { head :status => :ok } else format.html { render :action => "new" } format.xml { render :xml => @conversion.errors, :status => :unprocessable_entity } end end This way, the browser gets a non-existent .gif image. Is there a better way to do this?

  • How to set a predefined value in a form in Rails

    - by marco
    So I just got started in Rails, and I'm trying to create an Object (a book_loan in my case) with a Form. The thing is that I get to this form by clicking on a book, so I pass the book_id as a parameter, like localhost:3000/loans/new?id=1. Now I don't want the user to be able to set the book id field in the form, since I already know the id. So my question is how to set the value in the form. I have been trying things like: <% form_for(@loan) do |f| %> <%= f.error_messages %> ... <%= @loan.book_id = params[:id] %> <%= f.submit 'Create' %> <% end %> without any success. Does anybody have a hint for me?

  • RSpec View testing: How to modify params?

    - by sebastiangeiger
    I am trying to test my views with RSpec. The particular view that is causing me troubles changes its appearance depending on a url parameter: link_to "sort>name", model_path(:sort_by => 'name') which results in http://mydomain/model?sort_by=name My view then uses this parameter like that: <% if params[:sort_by] == 'name' %> <div>Sorted by Name</div> <% end %> The RSpec looks like this: it "should tell the user the attribute for sorting order" do #Problem: assign params[:sort_for] = 'name' render "/groups/index.html.erb" response.should have_tag("div", "Sorted by Name") end I would like to test my view (without controller) in RSpec but I can't get this parameter into my params variable. I tried assign in all different flavours: assign[:params] = {:sort_by => 'name'} assign[:params][:sort_by] = 'name' ... no success so far. Every idea is appreciated.

  • How can I make an aggregated property support ActiveRecord::Dirty semantics?

    - by Eric
    I have an aggregated attribute which I want to be able ask about its _changed? ness, etc. composed_of :range, :class_name => 'Range', :mapping => [ %w(range_begin begin), %w(range_end end)], :allow_nil => true If I use the aggregation: foo.range = 1..10 This is what I get: foo.range # => 1..10 foo.range_changed? # NoMethodError foo.range_was # ditto foo.changed # ['range_begin', 'range_end'] So basically, I'm not getting ActiveRecord::Dirty semanitcs on aggregated attributes. Is there any way to do that? I'm not having a lot of luck with alias_attribute_with_dirty, etc.

  • In Rails 3, how does one render HTML within a JSON response?

    - by ylg
    I'm porting an application from Merb 1.1 / 1.8.7 to Rails 3 (beta) / 1.9.1 that uses JSON responses containing HTML fragments, e.g., a JSON container specifying an update, on a user record, and the updated user row looks like . In Merb, since whatever a controller method returns is given to the client, one can put together a Hash, assign a rendered partial to one of the keys and return hash.to_json (though that certainly may not be the best way.) In Rails, it seems that to get data back to the client one must use render and render can only be called once, so rendering the hash to json won't work because of the partial render. From reading around, it seems one could put that data into a JSON .erb view file, with <%= render partial % in and render that. Is there a Rails-way of solving this problem (return JSON containing one or more HTML fragments) other than that? In Merb: only_provides :json ... self.status = 204 # or appropriate if not async return { 'action' => 'update', 'type' => 'user', 'id' => @user.id, 'html' => partial('user_row', format: :html, user: @user) }.to_json In Rails?

  • Rails how to return a list of answers with a specific question_id

    - by mytwocentsisworthtwocents
    Let's say I have two Models, Answers and Questions (there are others, but irrelevant to the question). The models are as follows: Answer.rb class Answer < ActiveRecord::Base attr_accessible :description, :question_id has_one :question, :through => :user, :dependent => :destroy validates :description, :presence => true end Question.rb class Question < ActiveRecord::Base attr_accessible :budget, :description, :headline, :user_id, :updated_at, :created_at belongs_to :user has_many :answers validates :headline, :description, :user_id, :presence => true end I'd like to display on a page a list of all answers associated with a question, and only those questions. I got this far. I believe this variable finds all the questions in the database by the question_id (foreign key): @findanswers = Answer.all(params[:question_id]) And this one grabs the the id of the current question (this code will reside as an ERB on the page where the current question is located): @questionshow = Question.find(params[:id]) And now I'm stuck. How do I put the two together so that I list all the answers with the current question id?

  • Replace all URL unless it is allowed

    - by ratamaster
    I had a regex that replaced all URLs from a given string: my_string = "www.example.com test www.mysite.com" my_string.gsub!(/[a-zA-Z0-9\-\.]+\.(com|net|de|org|uk|biz|info|co.uk|es|de)(\/\S*)?/i,'(site hidden)') As a result of the above I get: "(site hidden) test (site hidden)" How could I change the regex to not replace www.mysite.com ??? It means that the replace should output "(site hidden) test www.mysite.com" Thanks !

  • Rails passenger production cache definition

    - by mark
    Hi I'm having a bit of a problem with storing data in rails cache under production. What I currently have is this, though I have been trying to work this out for hours already: #production.rb config.cache_store = :mem_cache_store if defined?(PhusionPassenger) PhusionPassenger.on_event(:starting_worker_process) do |forked| if forked Rails.cache.instance_variable_get(:@data).reset end end end I am using a cron job to (try to) save remote data to the cache for display. It is logged as being written to the cache but reportedly null. If anyone could point me toward a decent current tutorial on the subject or offer guidance I'd be extremely grateful. This is really, really frustrating me. :(

  • Can you call compiled JRuby classes from java?

    - by John Baker
    So I came up with the general idea to write some code in JRuby, then access all the classes via Java. I have no idea if this is at all possible but I wanted to ask anyway. Lets say I have some JRuby code: class adder def addme return 22 end end If I compiled this with jrubyc is there any way I could then possibly do something like this in java: import adder; class anything { void testMethod() { adder a = new adder(); int x = a.addme(); } } After looking at it now it sort of makes me think that Java will have zero idea what sort of item test addme is going to return so that might not work. I don't know but I wanted to throw it out there anyway. Thanks

  • Rails: Best practice to store user settings?

    - by ole_berlin
    Hi, I'm wondering what the best way is to store user settings? For a web 2.0 app I want users to be able to select certain settings. At the moment is it only when to receive email notifications. The easiest way would be to just create a Model "Settings" and have a column for every setting and then have a 1-1 relationship with users. But is there a pattern to solve this better? Is it maybe better to store the info in the user table itself? Or should I use a table with "settings_name" and "settings_value" to be completely open about the type of settings stored there (without having to run any migrations when adding options)? What is your opinion? Thanks

  • How do I pass objects through a _url based on a routing in rails?

    - by Angela
    I want to pass the attributes associated with two objects into a path created from a route. In this case, the _url is skip_contact_letter_url. contact_letter and letter are passed through a render partial. The clip below resides in the partial. <%= link_to_remote "Skip Letter Remote #{contact_letter}", :url => skip_contact_letter_url(contact_letter, letter), :update => "update-area-#{contact_letter.id}-#{letter.id}" %> <span id='update-area-<%="#{contact_letter.id}-#{letter.id}"%>'> </span> The route I created looks like this: map.resources :contact_letters, :member => {:skip => :post} And the controller looks like this: def skip @contact_letter = ContactLetter.new(params[:all]) @contact_letter.status = "skipped" @contact_letter.date_sent = Date.today #@contact_letter.date_created = Date.today if @contact_letter.save render :text => 'This letter was skipped!' end end When I look at the console, none of the parameters from contact_letter or letter get passed through.

  • Attributes passed to .build() dont show up in the query

    - by Sebastian
    Hi there guys! Hope your all enjoying your hollydays. Ive run into a pretty funny problem when trying to insert rows into a really really simple database table. The basic idea is pretty simple. The user selects one/multiple users in a multiselect which are supposed to be added to a group. This piece of code will insert a row into the user_group_relationships table, but the users id always @group = Group.find(params[:group_id]) params[:newMember][:users].each do |uid| # For debugging purposes. puts 'Uid:'+uid @rel = @group.user_group_relationships.build( :user_id => uid.to_i ) @rel.save end The user id always gets inserted as null even though it is clearly there. You can see the uid in this example is 5, so it should work. Uid:5 ... SQL (0.3ms) INSERT INTO "user_group_relationships" ("created_at", "group_id", "updated_at", "user_id") VALUES ('2010-12-27 14:03:24.331303', 2, '2010-12-27 14:03:24.331303', NULL) Any ideas why this fails?
