Re: [GSoC][New Feature] Editable and Read-only Columns - Mailing list pgadmin-hackers

 I updated the patch for backwards compatibility anyway.

Hi Yosry,

The previously mentioned issues seems to be fixed. Below are few issues:

1) On Python 2.7, I get below error when opening query tool:

2019-08-23 10:49:09,329: ERROR flask.app: Object of type buffer is not JSON serializable

    o.__class__.__name__)
TypeError: Object of type buffer is not JSON serializable

This error exists on the master branch on Python 2.7, it is not caused by the patch. It is also not a regression of my previous Query History Enhancement patch, I checked.

 

2) The patch is not compatible with older pyscopg2 (2.7.7). I get below error in View/Edit data.

2019-08-23 10:53:12,020: ERROR flask.app: 'table_column'
Traceback (most recent call last):

  File "/Users/adityatoshniwal/venv/pypg35/lib/python3.5/site-packages/flask/app.py", line 1799, in dispatch_request

  File "/Users/adityatoshniwal/projects/pgadmin4/web/pgadmin/tools/sqleditor/__init__.py", line 435, in poll
    columns = trans_obj.get_columns_types(conn)
  File "/Users/adityatoshniwal/projects/pgadmin4/web/pgadmin/tools/sqleditor/command.py", line 688, in get_columns_types
    table_oid=table_oid)
  File "/Users/adityatoshniwal/projects/pgadmin4/web/pgadmin/tools/sqleditor/utils/get_column_types.py", line 38, in get_columns_types
    if row['oid'] == col['table_column']:
KeyError: 'table_column'

I recall Dave mentioning that it is okay to use psycopg 2.8+ features and that it was a requirement of pgAdmin 4 now (clearly mentioned in requirements.txt too).

I did - then we had the whole table_oid issue on Debian/Ubuntu :-(

 

However, I updated the patch for backwards compatibility. Please find an updated patch attached.
