I have an application that has subtasks
, subattributes
, and weights
.
A subtask
can have many subattributes
via weights
and can have many weights
.
A subattribute
can have many subtasks
via weights
and can have many weights
.
A weight
can belong to both a subtask
and a subattribute
.
Right now I am trying to loop through the collection print the weight. However, I am having issues acutally figuring out how to get the specific weights. Here's what I have:
<% @subtasks.each do |subtask| %>
<% @subattributes.each do |subattribute| %>
<% if subattribute.subtasks.include (subtask) %>
#find the weight of that subattribute that's associated with that subtask
<% else %>
#create a new weight associated with the subattribute and subtask
<% end %>
<% end %>
<% end %>
Any suggestions. This is my first rails app and I didn't design the backend because I personally would have thought it easier to just have weight be a field in subattribute. Any help would be greatly appreciated.
Try this:
<% @subtasks.each do |subtask| %>
<% @subattributes.each do |subattribute| %>
<% if subattribute.subtasks.include?(subtask) %>
#find the weight of that subattribute that's associated with that subtask
<% Weight.where(subattribute_id: subattribute.id,subtask_id: subtask.id).first %>
<% else %>
#create a new weight associated with the subattribute and subtask
<% Weight.create(subattribute_id: subattribute.id,subtask_id: subtask.id) %>
<% end %>
<% end %>
<% end %>
