passing a parameter to the link_to method
How do you pass a parameter through the MVC using the link_to method?
view:
<%= link_to "Remove Tag", remove_tag_issue_path(issue)%&开发者_运维问答gt;
How do I use the link_to method, to utilize the remove_tag action?
issues_controller.rb
def remove_tag(parameter)
@issue.remove_it(parameter)
end
issue.rb
def remove_it(parameter)
self.users.delete(User.find(parameter))
end
In controller
def remove_tag
@issue.remove_it(params[:my_param])
end
And in view
<%= link_to "Remove Tag", remove_tag_issue_path(issue, :my_param => "Hello world")%>
In the view use the following
<%= link_to 'Remove Tag', remove_tag_issue_path(:issue => @issue)%>
and in controller
def remove_tag
@issue.remove_it(:issue => params[:issue])
end
