Ruby on Rails' respond_to causing strange error

由 瘦欲@ 提交于 2020-05-02 02:58:26
问题 There is another respond_to for the usual case, and a special case when a param[:top] is passed in, so there is another respond_to earlier in the code: respond_to do |format| format.html { render :top_page_analytics } format.json { render :json => @analytics } format.xml { render :xml => @analytics } return end but the above code actually gave a strange error for missing template for json, and further debug leading to: respond_to do |format| format.html { render :top_page_analytics } format

override to_xml to limit fields returned

由 旧时模样 提交于 2019-12-24 09:44:49
问题 using ruby 1.9.2 and rails 3, i would like to limit the fields returned when a record is accessed as json or xml (the only two formats allowed). this very useful post introduced me to respond_with and i found somewhere online that a nice way to blanket allow/deny some fields is to override as_json or to_xml for the class and set :only or :except to limit fields. example: class Widget < ActiveRecord::Base def as_json(options={}) super(:except => [:created_at, :updated_at]) end def to_xml

How to render js template from module included in controller?

由 China☆狼群 提交于 2019-12-22 10:38:16
问题 I have an action in a controller concern, which gets included in a controller. This action does not render a js.erb file as specified under a respond_to block. How do I properly get an action in a controller concern to successfully render a js.erb file (or any view, for that matter)? Is it a problem with my routes? The link for the module action = link_to image_tag("upvote.png"), send("vote_socionics_#{votable_name}_path", votable, vote_type: "#{s.type_two_im_raw}"), id: "vote-#{s.type_two_im

Rails respond_with — why does POST return a URL instead of the data?

由 梦想的初衷 提交于 2019-12-12 07:45:19
问题 This is a question "why does it work this way", not "how do I make this work". My app is calling a third party REST API that returns JSON, and returning the result as part of my own JSON API. I was using the Rails 3 respond_to and respond_with methods; in the case of GET requests, this works as I expect, just passing through the JSON. In the case of POST , it does more, including making a URL from the object returned to pass in a :location option. But since my object is just JSON (not
