I am passing several params from my view but need to put some logic
behind one of them. I pass a value of either "Yes" or "No"
from my view
to the controller with the param known as "completed" under
"update".
Here is my controller and view which works fine:
view->
<%= form_tag :action => ''update'', :id => @project
%>
<% form_for :project do |f| -%>
<table>
<tr>
<td><label for= "name">Project Name</label>
<%= f.text_field :name %>
</td><td>
<%= f.label :completed %>
<%= f.select(:completed, ["No", "Yes"] )%>
</td></tr></table>
<%= submit_tag ''Submit'' %>
<%= form_tag %>
<% end -%>
controller->
def update
@project = Project.find(params[:id])
if @project.update_attributes(params[:project])
redirect_to :action => ''index'', :id => @project
else
render :action => ''edit''
end
end
I would like to add some logic to do something if the "completed"
param
is equal to "Yes". Here is my attempt but it doesn''t work:
def update
@project = Project.find(params[:id])
if @project.update_attributes(params[:project])
if params[:completed] == "Yes" do "something here" end
redirect_to :action => ''index'', :id => @project
else
render :action => ''edit''
end
end
Can anyone help me put some logic in for just the value of the completed
param?
thanks

If it is just a syntax error that is because you have not got the syntax for ''if'' right, it should be if params[:completed] == "Yes" ..... end Note however that you are doing it *after* the record is saved, which happens in update_attributes. If you are trying to do it before the save then move it up to before the update. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi, You can remove the form_tag. form_for will create that for you. Then use something like: f.label :completed f.select(:completed, [[''Yes'', true],[''No'', false]]) Presumably Project has a boolean field called ''completed'' with probably a :default => false on the migration. Once you''ve updated your attributes you should probably just use: if @project.completed? # do something clever here... end On 8 March 2011 16:07, A.
