Wasn''t sure what to call the subject, but here''s my issue.
I''ve got two models, and for arguments sake they''re called
model1 and
model2. model1 has many models2 and therefore I use the following
within the ''model'' files
model1
has_many :models2
model2
belongs_to :model1 .......etc
However on my HTML listing page I want to show all the model1''s and
their model2 associates. For example,
model1 (foo1)
model2 (bar1)
model2 (bar2)
model2 (bar3)
model1 (foo2)
model2 (bar4)
model2 (bar5)
model2 (bar6)
model2 (bar7)
So far I''ve only ever displayed one model and then used association to
get it''s children, for example
@model1 = Model1.find(params[:id])
@model2 = @model1.model2.find(:all)
The above works nicely, however for my new project I do;
@model1 = Model1.find(:all)
@model2 = Model2.find(:all)
I loop over @model1 and then have to loop on @model2 to see whether
any of them belong to the @model1 I''m currently reading. Is their a
nicer way to ''filter'' @model2 into a new variable containing
only the
items relating to the current @model1? I just want my code to be
cleaner and more ''rubyfied''
Thanks in advance

I don''t believe so because model1 is an array of database values, and the relationship to model2 is a one to many. At the moment I i''ve got @model1s = Model1.find(:all) @model2s = Model2.find(:all) When I render out each of the entries in @model1s I have to loop over @model2s in order to find the related values and render those. Normally if I''d only got one value, i.e. not an array, within @model1 then I would do @model1 = Model1.find(1) @model2 = @model1.model2.find(:all) To bottom line it I was just hoping these was a nice rubyish/rails way of handling this. Thanks for you reply and hopefully the above makes things a little clearer.
