Hi,
I have a CSV upload option and need to create a table and model based on
the CSV colums.
We allow to upload different kind of CSV file formats and each file upload
will create new table and info will be stored accordingly. I have created a
table with columns based on CSV file header and also created a model base
on CSV file name. But when i store the file details to specific table i
faced error.
def self.import(file, head, csvalue,fname)
...............
..............
ActiveRecord::Schema.define do
create_table "#{fname}" do |t|
#(define your columns just as you would in a migration file)
head.each do |h|
t.text h
end
# t.string :my_string
end
end
model_file = File.join("app", "models", fname.singularize+".rb")
model_name = fname.singularize.capitalize
File.open(model_file, "w+") do |f|
f << "class #{model_name} < ActiveRecord::Base\nend"
end
# ss=model_name.new
* p ss=model_name.constantize.new*
..............
...............
file="#{fname}_#{cnt}"
return file
end
How can declare the object for dynamic model. Because I couldn't store the
values to new table.
I faced the *Error* like *NameError (uninitialized constant Mytest):*
Any idea how to solve this ?
