After processing data inside model,how to insert processed data(interest_to_be_paid etc) to database

Rails
1

class Recovery < ActiveRecord::Base
def self.processrecovery
@members = Member.where(record_status: “1”)
@members.each do |member|
tmemberCode = member.member_code
:
:
:# Processing of data from different database
:
:
# Variables containing processed data
interest_to_be_paid
pInstallmentAmt = tPersonalLoanBalAmt * tpersonalintrate / (100 *
12)
jInstallmentAmt = tJointLoanBalAmt * tjointintrate / (100 * 12)
end
end

Now how can I insert these processed data into recoveries table?
Should I user

Recovery.create(interest: => interest_to_be_paid, p_installement: =>
pInstallmentAmt,…)

inside recovery.rb (model) itself?

Why not? Presumably inside processrecovery.

I didn’t get you. Do you mean I can use Recovery.create(…) directly
inside processrecovery without sending them to controller?

If so how can I use params? Because I suspect Rails 4 won’t let me to
directly insert data to tables without using strong parameters by
permitting them.

Thank you.

Of course, see section 5 of

In Rails 4 the protection has been moved out of the model and into the
controller. You can do anything you like while manipulating models
directly rather than through controllers.

Sound like good new for me even though it is not recommended.

What is it you believe is “not recommended”?

I mean that I’m not using association between tables when it is possible
to
easily cascade changes done in one table, And I’ve not seen anywhere
inserting records through model directly and it’s not even showed as
example in rails guides.

So I think the way of coding that I’m doing has to be improved and code
has
to be optimized.

I’m afraid I don’t understand that sentence,

?? From your original example:

class Recovery < ActiveRecord::Base
def self.processrecovery
# do whatever
create(interest: interest_to_be_paid, p_installment:
pInstallmentAmt)
end
end

And there you go, you’ve created a new Recovery object and saved
it to the database.

Try thinking less in terms of “tables” and more in terms of “objects”
and let ActiveRecord do its job as ORM :slight_smile:

FWIW,
