  • Rendering HTML in rails without actually displaying it

    - by Kevin Whitaker
    Hello all, My current project requires me to assemble a .zip file containing HTML and text-only templates for a user to download, for importing into an email marketing program. I've inherited this project, and currently the code uses a "fake" model (that is a model that does not directly correlate to a database table), in which it stores the entire template in a string, using dynamic variables to populate certain areas. The "fake" model then has a method for creating a zip file. It seems to me that there has to be a better way to do this. I was wondering if there was a way to move the template into a .erb/haml file, and then write a method that would populate the file in preparation for being zipped up? Basically, is there a way to render an HTML and text file, without actually having to display them? Thanks for any help.

  • HABTM checking for match of latest 3

    - by user333614
    Here's an interesting one for you folks... I have a HABTM (has_and_belongs_to_many) relationship between "Dogs" and "Trips". My goal is to find two result sets: 1) Dogs that have been on at least 1 of the last 3 trips and call that @dogs_current 2) Dogs that have NOT been on any of the last 3 trips and call that @dogs_old I found that I can find what the last 3 trips are by doing this in the Trip model: named_scope :last3, :order => 'date DESC', :limit => 3 But not sure how to use that list get 1 and 2. This hack works, but it seems ugly. There must be a better way! :) @dogs_current = [] @dogs_old = [] @dogs.each do |dog| if (Trip.last3 - dog.trips).size < 3 then @dogs_current << dog else @dogs_old << dog end end Any ideas? Thanks! -Cam

  • asset_packing tiny_mce files

    - by haries
    I use inplacericheditor plugin and tiny_mce Before asset_packager usage, this is how I include the files and they work well <script src="/javascripts/patch_inplaceeditor_1-8-2.js" type="text/javascript"> </script> <script src="/javascripts/patch_inplaceeditor_editonblank_1-8-2.js" type="text/javascript" </script> <script src="/javascripts/tiny_mce/tiny_mce.js" type="text/javascript"></script> <script src="/javascripts/tiny_mce_init.js" type="text/javascript"></script> <script src="/javascripts/inplacericheditor.js" type="text/javascript"></script> My asset_packager.yml section looks like this for the above files: tinyeditor: patch_inplaceeditor_1-8-2 patch_inplaceeditor_editonblank_1-8-2 tiny_mce/tiny_mce tiny_mce_init tiny_mce/langs/en tiny_mce/themes/advanced/editor_template tiny_mce/themes/advanced/langs/en tiny_mce/plugins/save/editor_plugin tiny_mce/plugins/autoresize/editor_plugin tiny_mce/plugins/paste/editor_plugin tiny_mce/plugins/preview/editor_plugin tiny_mce/plugins/table/editor_plugin tiny_mce/plugins/contextmenu/editor_plugin tiny_mce/plugins/emotions/editor_plugin inplacericheditor When I include the asset_packaged file and load the page (in production) I get the following errors: "Ajax.InPlaceEditor is undefined" "Ajax.InPlaceRichEditor is not a constructor" Can anyone shed some light on where I am going wrong or share a better way to asset_package tinymce? Thanks!

  • form_form and custom parameter in path_prefix

    - by fguillen
    Hi people, I have this route: # config/routes.rb map.namespace :backshop, :path_prefix => '/:shop_id/admin' do |backshop| backshop.resources :items end And I want to use the form_for magic to reuse the same form on both: new and edit views: <% form_for [:backshop, @item] do |f| %> This used to works, and used to build a create url for the item or update url for the item depending on the status of the @item object. But this is not working on this case because the routes don't exists without the shop_id parameter, and I don't know how to say to the form_for something like this: <% form_for [:backshop, @item], :shop_id => @shop do |f| %> Because it tries to use the @item like the :shop_id parameter. Or like this <% form_for [:backshop, @shop, @item] do |f| %> Because it tries to build this url: backshop_shop_order_path I Know I can just to extract the form_for declaration from the partial and do different calls on depending if new or edit: <% form_for( @item, :url => backshop_items_path( @shop ) ) do |f| %> and <% form_for( @item, :url => backshop_item_path( @shop, @item ) ) do |f| %> But I just wanted don't do this because I have a bunch of models and is a few boring :) Thanks for any suggestion f.

    - by Trip
    I have over time, changed the size for thumbs of the class Deal. Through these changes, users were uploading to the site, so there are few people who have different sized thumbs. I wanted to reprocress or refresh these, so I went to into my root and typed: $ rake paperclip:refresh class=Deal Did nothing for the thumb sizes.. Then I : irb Deal.find(987).reprocess! Returned this : NoMethodError: undefined method `reprocess!' for #<Deal:0xb68a0988> from /data/HQ_Channel/releases/20100607130346/vendor/rails/activerecord/lib/active_record/attribute_methods.rb:260:in `method_missing' from (irb):7 My deal class is this : => Deal(id: integer, organization_id: integer, deal: string, value: string, what: string, description: string, image_file_name: string, image_content_type: string, image_file_size: integer, image_updated_at: datetime, created_at: datetime, updated_at: datetime, deal_image_file_name: string, deal_image_content_type: string, deal_image_file_size: integer, deal_image_uploaded_at: datetime) What can i do to have it reprocess the original to make the thumb the correct size in the current thumb size params?

  • Cant use with clauses in find_by_sql

    - by PaulMurrayCbr
    Activerecord seems to be peeking at my sql and getting it wrong. I am finding that this: sql = " select etn.* from edittree_name etn where id = #{id}" Name.find_by_sql(sql) works, but this: sql = " with pp as ( select * from dual) select etn.* from edittree_name etn where id = #{id}" Name.find_by_sql(sql) Gives me a "undefined method `each' for 1:Fixnum". Any clues? Is there a "find_by_raw_sql (and don't try to understand it yourself)" method?

  • Rails: How to preload a message to user

    - by Michael
    I have a Rails based prelaunch site that has some rotating background images (which are important for selling the idea of the site) that are taking too long to load, such that the users are leaving the site before they load. The only thing they're seeing is the email submission box. What's a good way to show a message to the users that the site will take some time to load but then have that message disappear after a reasonable period of time. I'm guessing a jQuery fadeOut() with a timer, but I'm not sure how long to set the timer for, because I'm not sure at what time it would start counting. Any suggestions?

  • ActiveRecord find all parents that have associated children

    - by brad
    I don't know why I can't figure this out, I think it should be fairly simple. I have two models (see below). I'm trying to come up with a named scope for SupplierCategory that would find all SupplierCategory(s) (including :suppliers) who's associated Supplier(s) are not empty. I tried a straight up join, named_scope :with_suppliers, :joins => :suppliers which gives me only categories with suppliers, but it gives me each category listed separately, so if a category has 2 suppliers, i get the category twice in the returned array: Currently I'm using: named_scope :with_suppliers, :include => :suppliers and then in my view I'm using: <%= render :partial => 'category', :collection => @categories.find_all{|c| !c.suppliers.empty? } %> Not exactly eloquent but illustrates what I'm trying to achieve. Class Definitions class SupplierCategory < AR has_many :suppliers, :order => "name" end class Supplier < AR belongs_to :supplier end

  • Rails layouts per action?

    - by mrbrdo
    I use a different layout for some actions (mostly for the new action in most of the controllers). I am wondering what the best way to specify the layout would be? (Consider like I am using 3 or more different layouts in the same controller) I don't like using render :layout = 'name' that much. I did like doing layout 'name', :only = [:new] but it turns out I can't use that to specify 2 different layouts (e.g. if I call layout 2 times in the same controller, with different layout names and different only options, the first one gets ignored - those actions don't display in the layout i specified). I'm using Rails 2.

  • Multiple row insertion in a faster way

    - by Cyborgo
    Hi, I am using rails and I am trying to insert new rows into the table. The data comes from a text file and I created hash with one of the attribute as key. Then I find all the keys that are currently not in the table. Then I need to insert all of them into the table with all the attributes that I saved in hash. newvals.each{ |x| author = Author.create(:first => x, :second => hash[x][0], :third => hash[x][1]) author.save } This has lot of overhead as it makes an SQL update one at time. The newals array is usually quite big around the size of 20-30k. I know create can insert multiple objects at once, but I cant seem to figure out how. Is there any way to get this done. Thanks.

  • What is Rails way to DRY up the controller pattern of verifying :id is for a valid object (else redirect to error page)

    - by jpwynn
    One of my controllers has close to 100 methods (eg routes) and nearly every one starts out the same code to redirect to an error page if the id param is invalid, followed by a similar check if the user that id doesn't belong in the user's account: def something @foo = Foo.find_by_guid(params[:id]) unless @foo @msg ||= { :title => 'No such page!', :desc => "There is no such page!" } render :action => "error" and return end unless @foo.owner_id == current_user.id @msg ||= { :title => 'Really?', :desc => "There is no such page." } render :action => "error" and return end What is the best way to DRY up that sort of page id and owner id validation, given the code is doing a render ... and return? What I don't want to do at this point is offload it to a blackbox roles and permissions library like CanCan... my goal is simply to have the in-app code to handle this be as clean as possible.

  • Destroy? Delete? What's going on here? Rails 2.3.5

    - by Steve
    I am new to rails. My rails version is 2.3.5. I found usage like: In controller, a destroy method is defined and in view, you can use :action = "delete" to fire that method. Isn't the action name has to be the same as the method name? Why delete is mapped to destroy? Again, in my controller, I define a method called destroy to delete a record. In a view, I have <%= link_to "remove", :action = 'destroy', :id = myrecord %. But it never works in practice. Every time I press the remove link, it redirects me to the show view, showing the record's content. I am pretty sure that my destroy method is: def destroy @myobject = MyObject.find(params[:id]) @myobject.destroy @redirect_to :action = 'index' end If I change the method name from destroy to something like remove_me and change the action name to remove_me in the view, everything works as expected. In the above two wired problems, I am sure there is no tricky rountting set in my configuration. All in all, seems the destroy and delete are mysterious keywords in rails. Anyone can explain this to me? Thank you very much.

  • How Would you Mimic an Arbitrary Directory Structure with Rails Routes?

    - by viatropos
    I want to be able to map Google Docs' folder system to urls in my application and am just wondering how I can say "route, I want you to match an arbitrary set of nodes, and the last one is the file (or possibly a directory, I can check in the controller)". So I could do things like: www.mysite.com/documents/folder1/childfolderA/document www.mysite.com/documents/root-level-doc Can the routes.rb file do something like this?

  • Rails Functional test assert_select javascript respond_to

    - by Macint
    Hello, I am currently trying to write functional tests for a charging form which gets loaded on to the page via AJAX(jQuery). It loads the form from the charge_form action which returns the consult_form.js.erb view. This all works, but I am having trouble with my testing. In the functional I can go to the action but I cannot use assert_select to find a an element and verify that the form is in fact there. Error: 1) Failure: test_should_create_new_consult(ConsultsControllerTest) [/test/functional/consults_controller_test.rb:8]: Expected at least 1 element matching "h4", found 0. <false> is not true. This is the view. consult_form.js.erb: <div id="charging_form"> <h4>Charging form</h4> <div class="left" id="charge_selection"> <%= select_tag("select_category", options_from_collection_for_select(@categories, :id, :name)) %><br/> ... consults_controller_test.rb: require 'test_helper' class ConsultsControllerTest < ActionController::TestCase def test_should_create_new_consult get_with_user :charge_form, :animal_id => animals(:one), :id => consults(:one), :format => 'js' assert_response :success assert_select 'h4', "Charging form" #can't find h4 end end Is there a problem with using assert_select with types other than html? Thank you for any help!

  • Is it possible to have variable find conditions for both the key and value?

    - by DarrenD
    I'm trying to pass in both the field and the value in a find call: @employee = Employee.find(:all, :conditions => [ '? = ?', params[:key], params[:value].to_i) The output is SELECT * FROM `employees` WHERE ('is_manager' = 1) Which returns no results, however when I try this directly in mysqsl using the same call without the '' around is_manager, it works fine. How do I convert my params[:key] value to a symbol so that the resulting SQL call looks like: SELECT * FROM `employees` WHERE (is_manager = 1) Thanks, D
