Update column migration method to correctly set null: false

[srt32]

• Update MainAdapter#create_table to call add_spatial_column

Edit: Here is more specific information (taken from a comment that is now deleted):

Previously running

create_table :my_table do |t|
  t.column :geometry, :geometry, null: false
end

would produce a table with the geometry column without null: false. With this update, including the null: false flag will now set the column to be null: false as expected.

This is great. Thanks.

The add_spatial_column signature is confusing, though:

def add_spatial_column(column_name, table_name, info = {}, type = nil, options)

# called by:
add_spatial_column(column_name, table_name, options)

While this works, it's confusing in that the info and type arguments get their default value, and the options argument maps to options. That is weird since the 3rd argument in the method call is mapped to the 5th argument in the signature.

I think the right solution to that is to combine the info and options hashes as the last argument & move the type munging into add_column. Any thoughts about that?

(I suppose I can merge this and we can fix it as a separate PR... )

I agree we should clean up the signature and combine info and options (and
maybe remove type from options and require it as an input). I would vote
for doing that in a separate PR as I consider this PR a bug fix and the
other as more of a refactoring. I'm fine to fix it up in here if you prefer
though.

Yep, let's clean up the add_spatial_column method in a separate PR.

Sounds good. I should be able to take a stab at it this week.

Great - as always, check the latest master first since I may hack on it some too.

Hey guys, still not sure how to use this. How would I use add_spatial_column to add a polygon column using srid 4326?

[teeparham]

@jeremieweldin this is an old, closed issue that applies to the internals of the adapter. Check the readme for version 2 or 3, depending on which version of rails you're using. There are examples for adding polygon columns there.

Sorry about that... limited results from the google search. :/ I will look into the readme. Thanks!
