Question

I am having troubles with an RSPec test. The test does a PUT with some objects in the request. The controller which receives the PUT seems to be not getting the correct values

For example, ‘put :update, :id => @channel.id, :channel => @channel, :tags => @tag’ Then, in the Controller, when I try to use params[:tags] there is an integer in that location. A Gist with the Spec and the controller method is at https://gist.github.com/3715021

This started happening when I upgraded from Rails 3.0.13 to 3.1.8

Any idea what might be happening here and how to resolve it?

I’m assuming that @tag is an object from your Tags model. When you give Rails an object like

`get :action, :foo => foo`

or in a url helper (e.g., foo_path(foo)),

Rails will turn your object into a parameter suitable for use in a url via the #to_param method. You’re probably getting an integer because Tag#to_param returns the id of the tag in your db.

It looks like your update action, by contrast, expects params[:tags] to be a hash, presumably generated from a form that includes fields for values like tags[:name].

I can’t help much more without knowing more about the relevant code. But I’m guessing what you want to do is change your test to read

put :update, :id => @channel.id, :channel => @channel, :tags => { :name => 'tag' }

or something like that, mimicking the params you’d get by actually submitting the form that PUTs to your update action.
