In my application I have to tables
- Student
- Alma Mater Department
Student table belongs_to :alma_mater_department and Alma Mater
Department has_many :students
Firstly, I want to predefined some data in seeds.rb for Alma Mater
table which I want to look like this
++++++++++++++++++++
- Type | Name +
++++++++++++++++++++ - B.Tech | Mechanical +
-
| Production + -
| Electronics +
++++++++++++++++++++
- M.Tech | Mechanical +
-
| Production + -
| Electronics +
++++++++++++++++++++
What is the best approach of doing this kind of seeding (as it has
many repeating values)
Secondly, once done with above step, I want that under student’s
new.html.erb there will be two <collection_select> fields
- Where user can choose from Type
- Where user can choose from Name
Say, user choose value == B.Tech Production (which according to table
is id=2). How to send that id thing in Student table and display them.
P.S: My problem is bit topsy turvy kinda thing. Please bear with me as
I am leaning these concepts.
