i am designing a dashboard page that summarizes data from multiple models, all on one page. and i also want to include forms on that page for creating new items.
after some experimenting, i realized i needed some advice as to the best practice for this situation... here are the 2 methods i was attempting
1) using nested field_fors...
form_for @job do |j|
j.fields_for :invoice do |i|
i.fields_for :charges do |c|
c.text_field :amount
or 2)
form_for @job.invoice.charges.build do |c|
c.text_field :amount
with the nested approach, the problem is now i have a new object which throws a wrench in my show view when it iterates through existing objects. suddenly trying to render all the created_at times fails since the new object hasn't been saved yet.
the problem with approach 2) is either i post each form to its own controller to handle it, but if it doesnt validate, i need to render the show view... which means i have to provide each controller i have a form for with all the instance variables and methods etc to render the page.
and i havent quite figured out how the error handling works. sometimes my form is marked with fieldWitherrors class, and sometimes it doesnt. i have been trying out both approaches but am having trouble figuring it out.
can anyone offer advice on the direction i should go here?
