Hi,

data['form'] = self.read(cr,uid,ids,['alphalist_category_type','a_alpha_type','fiscalyear_id']

Above line tells that data['form'] having list of the records which are return by the read method. So, the data is looks like below.

data['form'] is like : [{'id':1,'alphalist_category_type':'xx', . . .}, {'id':2,'alphalist_category_type':'xx', . . .}, {'id':3,'alphalist_category_type':'xx', . . .}]

So, when you have access it like : year1 = data['form']['fiscalyear_id'] 

In the above statement of course we are receiving an error as you have "TypeError: list indices must be integers, not str".

You can do two things.

1) Using loop you can access like below :

for data_form in data['form']:

    # your code in that you can get data 

    year1 = data_form['fiscalyear_id']  # If 'fiscalyear_id' is many2one field then you will get the data like (Id, name). To get the Id you have to wirte down data_form['fiscalyear_id'][0] and for its name data_form['fiscalyear_id'][1].

2) You can get the data like :

year1 = data['form'][0]['fiscalyear_id']  #It will give you the data of first record.

I hope you will get this answer and it is helpful to you.
