Ruby on Rails: Retrieve css element and check value - css

Question

I think this is a pretty straight forward question so I'll get to it:
subject.rb
def current_step
#current_step || steps.first
end
def steps
if #title = 'Baseline'
%w[sfmfa phq whoqol_bref positive_negative mses_self pam spsir change_questionnaire prosthesis cognitive comorbidity pain mspss audit ]
elsif #title = 'Treatment Completion'
%w[smfa phq whoqol_bref positive_negative pam spsir ssscq prosthesis pain complications mspss audit ptcs accessing_resources satisfaction ]
else
redirect_to #subjects_path
flash[:notice] = "Did not find title"
end
end
I'm trying to check the value of the Title element on my tc.html.erb webpage (this should return 'Treatment Completion'). At the moment the check isn't working, and I end up with the steps defined under 'Baseline' every time.
I have steps for a paginated form, and it all works for the Baseline page, so now I'm trying to pass a different set of elements as the steps definition for a different page.
I think I'm using the wrong accessor (#title). This ruby I'm using to provide the Title is:
<% provide(:title, 'Baseline') %>
Any input would be appreciated.

Answer 1

Well there are a couple of things that are wrong. The first thing is that you're trying to use redirect_to in a model. This should be used in a controller. Second, #subjects_path is not an instance variable, it's a url helper, so that should not have an # sign before it. Third, you're assigning, not comparing the if statement (using = and not ==).
So, to answer the original question, you could fix your original problem by:
def steps
if #title == 'Baseline'
%w[sfmfa phq whoqol_bref positive_negative mses_self pam spsir change_questionnaire prosthesis cognitive comorbidity pain mspss audit]
elsif #title == 'Treatment Completion'
%w[smfa phq whoqol_bref positive_negative pam spsir ssscq prosthesis pain complications mspss audit ptcs accessing_resources satisfaction]
else
redirect_to #subjects_path
flash[:notice] = "Did not find title"
end
end
Note that that only fixes the third error.
