I need it to retrieve fields from the database dynamically according
to the current language,
Please refer to the example below:

MODEL:
......
Field('description_en', 'string',
    label=str(T('Image Description'))+" "+str(T('EN')),
    requires=[IS_NOT_EMPTY(), IS_LENGTH(maxsize=250, minsize=0)]
),
Field('description_ar', 'string',
    label=str(T('Image Description'))+" "+str(T('AR')),
    requires=[IS_NOT_EMPTY(), IS_LENGTH(maxsize=250, minsize=0)]
),
......

CONTROLLER:
......
query = eval('db.image.description_'+lang)
records = db(db.image.project_id==project_id).select(query AS
description)
...

VIEW: (One view for all languages)
......
{{for record in records:}}
{{=record.description}}
{{pass}}
......

However, I solved the problem by modifying the code as follows:

CONTROLLER:
......
query = eval('db.image.description_'+lang)
records = db(db.image.project_id==project_id).select(query)
...

VIEW:
......
{{for record in records:}}
{{=eval('record.description_'+lang)}}
{{pass}}
......

Regards,
