If no template is available, the behavior - # depends on the selected format: - # - # * for an html response - if the request method is +get+, an exception - # is raised but for other requests such as +post+ the response - # depends on whether the resource has any validation errors (i.e. - # assuming that an attempt has been made to save the resource, - # e.g. by a +create+ action) - - # 1. If there are no errors, i.e. the resource - # was saved successfully, the response +redirect+'s to the resource - # i.e. its +show+ action. - # 2. If there are validation errors, the response - # renders a default action, which is <tt>:new</tt> for a - # +post+ request or <tt>:edit</tt> for +patch+ or +put+. - # Thus an example like this - - # - # respond_to :html, :xml - # - # def create - # @user = User.new(params[:user]) - # flash[:notice] = 'User was successfully created.' if @user.save - # respond_with(@user) - # end - # - # is equivalent, in the absence of <tt>create.html.erb</tt>, to - - # - # def create - # @user = User.new(params[:user]) - # respond_to do |format| - # if @user.save - # flash[:notice] = 'User was successfully created.' - # format.html { redirect_to(@user) } - # format.xml { render xml: @user } - # else - # format.html { render action: "new" } - # format.xml { render xml: @user } - # end - # end - # end - # - # * for a JavaScript request - if the template isn't found, an exception is - # raised. - # * for other requests - i.e. data formats such as xml, json, csv etc, if - # the resource passed to +respond_with+ responds to <code>to_<format></code>, - # the method attempts to render the resource in the requested format - # directly, e.g. for an xml request, the response is equivalent to calling - # <code>render xml: resource</code>. - # - # === Nested resources - # - # As outlined above, the +resources+ argument passed to +respond_with+ - # can play two roles. It can be used to generate the redirect url - # for successful html requests (e.g. for +create+ actions when - # no template exists), while for formats other than html and JavaScript - # it is the object that gets rendered, by being converted directly to the - # required format (again assuming no template exists). - # - # For redirecting successful html requests, +respond_with+ also supports - # the use of nested resources, which are supplied in the same way as - # in <code>form_for</code> and <code>polymorphic_url</code>. For example - - # - # def create - # @project = Project.find(params[:project_id]) - # @task = @project.comments.build(params[:task]) - # flash[:notice] = 'Task was successfully created.' if @task.save - # respond_with(@project, @task) - # end - # - # This would cause +respond_with+ to redirect to <code>project_task_url</code> - # instead of <code>task_url</code>. For request formats other than html or - # JavaScript, if multiple resources are passed in this way, it is the last - # one specified that is rendered. - # - # === Customizing response behavior - # - # Like +respond_to+, +respond_with+ may also be called with a block that - # can be used to overwrite any of the default responses, e.g. - - # - # def create - # @user = User.new(params[:user]) - # flash[:notice] = "User was successfully created." if @user.save - # - # respond_with(@user) do |format| - # format.html { render } - # end - # end - # - # The argument passed to the block is an ActionController::MimeResponds::Collector - # object which stores the responses for the formats defined within the - # block. Note that formats with responses defined explicitly in this way - # do not have to first be declared using the class method +respond_to+. - # - # Also, a hash passed to +respond_with+ immediately after the specified - # resource(s) is interpreted as a set of options relevant to all - # formats.
