  • How do I best run a search on Date when it is not a :has_many association?

    - by Angela
    I have a number of activities that have a calculated scheduled date. The activities, for example, Email, have a email.days method which is the days from a Contact.start_date on which it should be sent. This means contact.start_date + email.days yields a date on which email is sent to contact. I would like to use link_to around the date, so I can see all the emails and associated contacts that are to be scheduled on that date. However, this "date" is not an attribute or an associate, so I'm not linking to a model's view. It's calculated. So: 1) What should the actual "format" of the date that gets passed in the URl be? What is the method to do the consistent conversion? 2) How do I (find) all instances, because this "date" is not an actual attribute, is it a calculated value which changes depending on the two associated models of Contact and Email. Thanks.

  • map.resource, parameter restrictions

    - by Tiago
    I've a controller :platform here. I'm trying to do something like: /:platform_name/ to redirect to its show, with the parameter. Here is what I've got: map.resource :platform, :as => ':platform_name', :platform_name => /pc|ps2|ps3|wii|ds|psp|xbox-360/ It's working fine. I've other neasted resources to it, and all them are accessing. But. The problem is, I've only those platform names, but when it doesnt fine another route, it aways fall on this. if I try /whatever/, it will look for the *platform_name = whatever*. I was expecting it to fall into the map.connect ':controller/:action/:id' rule. When I did *:platform_name = /pc|ps2|ps3|wii|ds|psp|xbox-360/*, wasnt expected that this rule only apply when the regular expression is fit? how could i restrict this?

  • Imagemagick Resizing in Paperclip

    - by jonathan.soeder
    So, I want to resize images to a FIXED width, but proportional height. I have been trying a wide range of operators: 380x242# 380x242 380!x242 380x242< none of them have the desired effect. Any help? I want it to fill or resize to the 380 width, then resize / shrink the height by the same factor it used to shrink or resize the image to 380 wide.

  • Random record in ActiveRecord

    - by astrofoo
    I'm in need of getting a random record from a table via ActiveRecord. I've followed the example from Jamis Buck from 2006. However, I've also come across another way via a Google search (can't attribute with a link due to new user restrictions): rand_id = rand(Model.count) rand_record = Model.first(:conditions => [ "id >= ?", rand_id]) I'm curious how others on here have done it or if anyone knows what way would be more efficient.

  • rails, activerecord callbacks not saving

    - by Joseph Silvashy
    I have a model with a callback that runs after_update: after_update :set_state protected def set_state if self.valid? self.state = 'complete' else self.state = 'in_progress' end end But it doesn't actually save those values, why not? Regardless of if the model is valid or not it won't even write anything, even if i remove the if self.valid? condition, I can't seem to save the state. Um, this might sound dumb, do I need to run save on it?

  • How do I use a custom cookie session serializer in Rack?

    - by Damien Wilson
    Hello SO. I'm currently integrating Warden into a new Rack application I'm building. I'd like to implement a recent patch to Rack that allows me to specify how sessions are serialized; specifically, I'd like to use Rack::Session::Cookie::Identity as the session processor. Unfortunately, the documentation is a little unclear as to what syntax I should use to configure Rack::Session::Cookie in my rackup file, can anyone here tell me what I'm doing wrong? config.ru require 'my_sinatra_app' app = self use Rack::Session::Cookie.new(app, Rack::Session::Cookie::Identity.new), {:key => "auth_token"} use Warden::Manager do |warden| # Must come AFTER Rack::Session warden.default_strategies :password warden.failure_app Jelli::Auth.run! end run MySinatraApp error message from thin !! Unexpected error while processing request: undefined method `new' for #<Rack::Session::Cookie:0x00000110124128> PS: I'm using bundler to manage my gem dependencies and I've likewise included rack's master branch as the desired version. Update: As suggested in the comments below, I have read the documentation; sadly the suggested syntax in the docs is not working. Update: Still no luck on my end; offering up a bounty to whoever can help me figure this out.

  • Sql query Error: Operand should contain 1 column(s) in rails

    - by dombesz
    Hi everyone, SELECT * FROM jobs WHERE (SELECT DISTINCT jobs.* FROM jobs, job_requests WHERE (jobs.user_id = 1) OR (job_requests.user_id = 1 AND job_requests.job_id = jobs.id)) This sql gives me Mysql::Error: Operand should contain 1 column(s). If i execute the select from the where clause it works SELECT DISTINCT jobs.* FROM jobs, job_requests WHERE (jobs.user_id = 1) OR (job_requests.user_id = 1 AND job_requests.job_id = jobs.id) Could somebody explain me why? This query is generated by rails activerecord so the main select is needed.

  • Multiple remote_form_for on the same page causes duplicate ids

    - by Ben Scheirman
    I've got a rails app that displays a list of items called modules. I'm iterating over these, rendering a partial for each one that includes a remote_form_for call. This all works, but fails HTML validation because my form text fields all have the same id. Is there a :prefix option on the form (or something else) I can use to get around this? Update: (some code) //_module_form.html.erb <% remote_form_for app_module do |f| %> <%= f.label :name %> <%= f.text_field :name %> <%= submit_tag 'Save' %> <%end %> //parent page <% @thing.modules.each do |app_module| %> <%= render :partial => "module_form", :locals => { :app_module => app_module } %> <% end %> So if I have more than 1 item in the collection, I render the identical form on the same page, and the form id and textbox id are duplicated. I can customize the form id pretty easily, but what about the text_box, since the controller is looking for specific named controls?

  • Decrease the load time for Mobile Version Rails Site

    - by Ramoji
    I have been working on the mobile version of my rails application.I am using the approach of using the same controller and rendering a mobile view when the request is from a mobile device. I am using jquery mobile in mobile views. For mobile views I did not use any layout for the views because it is the same as loading the required files in each view. In this approach, Every request essentially loads all of the required js,css files which i feel is making the mobile site to load slowly. How could i make my views to load the js and css files just once? Thanks, Ramoji.

  • How do I avoid nesting forms when offering inline editing of lists with checkboxes for mass updates.

    - by adam
    A lot of sites offer the ability to edit lists of items inline as well as allowing multiple items to be selected via checkboxes and have an action performed all at once e.g. delete, mark as spam etc. But how do you implement this without violating html rules. I need one form for the checkboxes with individual submit_tags for the mass actions. But after a user clicks on an item in the list, another form via Ajax will be inserted within the checkbox form. How do I avoid doing this? I'm using rails and jQuery.

  • Are there other search options for heroku

    - by Jonathan
    I am about to launch a beta site, and heroku looks like a great option. The only think that is getting me down is that the only search option is $20/mth for the Websolr add-on. I am sure that Websolr is great, but at this very early point in this project, I rather not light up that expense. Are there any free search options to couple with heroku's Blossom (free) plan. I feel like such a cheapskate!

  • intelligent thin start with port alias for bash

    - by seaofclouds
    i would like a single alias (ts) which starts my local development server. the script should test for an open port starting at 3000 and use the first available port. additionally, some sites require a rackup file, making -R config.ru necessary. this script should check the current directory for the config.ru file and add that to the alias if present. currently, to start my local development environment, i run: alias ts="thin -R config.ru -p 3000 start" often, i need to run several servers to test different sites, so i've created additional aliases: alias ts1="thin -R config.ru -p 3001 start"

    Hi all, I have some javascript making an ajax call in my Rails site: $.ajax({type: "PUT", url: url, data: { dummy: data }, complete: function(data) {}}); When Rails gets it, it throws back an ActionController::InvalidAuthenticityToken Error.

  • get next/previous month from a Time object

    - by tcurdt
    I have a Time object and would like to find the next/previous month. Adding subtracting days does not work as the days per month vary. time = Time.parse('21-12-2008 10:51 UTC') next_month = time + 31 * 24 * 60 * 60 Incrementing the month also falls down as one would have to take care of the rolling time = Time.parse('21-12-2008 10:51 UTC') next_month = Time.utc(time.year, time.month+1) time = Time.parse('01-12-2008 10:51 UTC') previous_month = Time.utc(time.year, time.month-1) The only thing I found working was time = Time.parse('21-12-2008 10:51 UTC') d = Date.new(time.year, time.month, time.day) d >>= 1 next_month = Time.utc(d.year, d.month, d.day, time.hour, time.min, time.sec, time.usec) Is there a more elegant way of doing this that I am not seeing? How would you do it?

  • Is it safe to put reference to current user in User model in Rails?

    - by Art Shayderov
    You know, I think I have to check current user in the model callbacks (like before_update). Rather than rely solely on adding where ('something.user_id = ?', 'current_user.id') in the controllers. I need something like Thread.CurrentPrincipal in .NET Is it safe to put reference to current user in User model? I'm sorry I don't really understand how it works under the hood yet. Or how you do it The Rails way? Sorry if this a silly question.

  • Can rails test speed be increased?

    - by Sam
    Hi all, I'm a recent convert to TDD but as my codebase grows in size and complexity, I find myself waiting longer and longer periods for the framework to load every time I want to run a test. I am aware of rspec's spec_server but I'm using Test::Unit with shoulda. I tried Snailgun (http://github.com/candlerb/snailgun) but noticed very little increased in speed. I have also tried spork-testunit (http://github.com/timcharper/spork-testunit) but it's not fully compatible with my existing tests. The delay in running tests is a definite pain point and is putting me of TDD (at least with rails). Is anyone aware of any other options? thanks Sam

  • Rails wiki highlight/strikethrough version differences between article versions

    - by mark
    Hi I'm wondering how to implement highlighting of changes to user edited articles on a wiki style rails project. Since articles may be fairly lengthy I'd ideally like strikethrough and highlighting, similar to github and wikipedia for example. Despite searching around the net I've not really come up with much, apart from instiki which is a complete wiki application. Thanks in advance for any advice.
