Display variable as method in an activerecord call?

Rails
1

Example:

def somemethod(variable)
value = Record.find(:all)
value.each do |row|
row.colone = “foo”
row.coltwo = “bar”
row.send(variable) = “keke”
row.save!
end
end

somemethod(colthree)

=> unexpected ‘=’, expecting kEND

I can’t do row.variable, that will create an undefined method. What can
I do to place in the expected column?

I figured it out myself.

def somemethod(variable)
value = Record.find(:all)
value.each do |row|
row.colone = “foo”
row.coltwo = “bar”
row[variable.to_sym] = “keke”
row.save!
end
end

Making the variable into a symbol works.

Do you want something like:

row.send(“#{variable}=”, “keke”)

If your meaning is to assign to a column whose name is supplied, then
you might also do:

row[variable] = ‘keke’

or even

row.write_attribute(variable, ‘keke’)
