Can not 'assigns' value in View test
by Shaker
::
Rate this Message:
Hello everyone:
I am quit new to View test using rspec. I want to write spec for a partial, which is rendered by a controller. However, the controller does not pass data to the partial using instance variables, it uses symbol variable instead. I read the example of view spec provided in the website. But the example is using instance variable. So I am looking for a way of assigning my test data to the partial to be tested. I would like to show an my code below: class MyController def index hash = {...#data provided here} render :partial=>'index', :layout=>false, :locals=>{:hash=>hash} end end _index.rhtml ......#unrelated code omitted <script> var data = <%= hash %>; <!-- process data here --> </script> In my spec, I used assigns[:hash] = my_own_data, but an error occurred, saying that "undefined local variable or method 'hash' ". How can I assign my own data to hash in my view spec? Thank you! |

Granted that I'm new too; however, assigns[:hash] creates a member
variable @hash that is made available to the view. Maybe that's the problem? Modify your view to use @hash instead.

Unfortunately, I am not supposed to change the code inside the partial. That's why I posted this message. I am trying to find a way of tackling this problem. Because I am going to test tens of hundreds of partials, most of which are using the symbols rather than instance variable.

I also feel puzzled. But that's what my colleagues do, and it works. The thing is they use
render :partial=>'index', :locals=>{:hash=>hash} in the controller to pass the hash data to the partial it will render(index in this case). And later they simply use <%= hash %> to get the hash data passed from the controller. Maybe the :locals does some magical work here. I am quite familiar with rspec and ruby. So I am reading more documentation now. Hopefully we could figure it out shortly.

OK - first: render :partial=>'index', :locals=>{:hash=>hash} Here, the symbol :hash is just a key - it is not the object that's been passed around. Second: <%= hash %> I'm assuming that's in the partial named index (a partial named index???????, now THAT's not at all confusing). In this case, the :locals => {:hash=>hash} in the calling template assigns the hash object (in the calling template's scope) as the return value of a method in the partial named .... (drum roll, please) .... hash. Like hash(). So - what you want to do is to stub the hash method on the template: template.stub!(:hash).and_return(the_hash_I_want_to_stick_in_the_template) That all make sense?

Hello, David:
Thank you very much for your help. Now it works! I would like to recall a message posted several days ago regarding the "paginate". How to test "paginate" in controller spec? One simple example may be like this: hash[:accounts_pages], hash[:accounts] = paginate :accounts(the table), #order and conditions follows How should I test this code in controller spec? Or can I mock this line, like should_receive(:paginate).and_return(...)? But the problem is 'paginate' returns two values. :( Thanks for investigating this question.
