I'm new to Ruby on Rails (and MVC) and am going around in circles trying to implement something. It relates to routing, and passing information from a button click on a static page to another class then rendering information from two different models (that have a relationship set up). Any help is much appreciated:-
So I generated users, matches and matchPicks scaffolds in rails on Nitrious.io and everything with them is fine. I think I understand most of how the routing goes re: GET, POST etc.
I then created a static page called blocks that has a number of buttons on it (Button 1 - 10). What I want to do is the following:-
- If the user clicks Button 1, relevant information on the matches (from the match model) in block 1 render as well as drop-down menus (from the match_picks model) that allow the user enter their team selection.
- If the user clicks Button 2, relevant information on the matches (from the match model) in block 2 render as well as drop-down menus (from the match_picks model) that allow the user enter their team selection.
- And so on.....
I think I have my relationships set up properly (see models code below) but my questions are:-
How do I pass information on what button was clicked (i.e. the block number) to the match_picks controller? And then how do I take that information in the match_picks controller and only display the relevant matches with the same block number?
Assuming I got the above working, I would only be displaying information from the match_picks database (in the match_pick/index view). How do I also show information from the match database in this view?
I'm pulling my hair out at this stage on how to implement it. I've read loads but am still so confused. I've posted some code below. If some other information is needed let me know.
Thanks for reading (and hopefully helping).

EDIT 1
I can't get it to pass the parameter. here's the relevant code:
In blocks.html.erb
<%= button_to "Match Block 1", matches_path(first_match: 1), :id => "open-contacts-dialog-btn", :class => "btn btn-large btn-primary", :method => :get %>
In matches_controller.rb
def index
if(params[:first_match].equal?(1))
@matches = Match.all
puts "The Test is true"
puts "The value of first_match is" + params[:first_match].to_s
else
@matches = Match.where(:id => 1..10)
puts "This test is false"
puts "The value of first_match is" + params[:first_match].to_s
end
end
The test keeps failing so enters the else and the debug line comes out as "The value of first_match is " (i.e. no value). I can't figure out why it's not passing the value of the parameter
Welcome to Rails!
To pass a variable to a controller you can simply add a parameter to the path like this :
<%= link_to 'Show', match_path(match_pick, id: my_value) %>
And you will get it in the controller like this
params[:id]
To display a different views with different models you can have a method in your controller like this :
def show
@match = Match.find(params[:id])
@match_picks = @match.match_picks
end
You can use it in your by simply calling @match or @match_pick. You can also display a different view by using the render method.
If you want to show a specific view for each block, you should create more views.
