This is not a static value, you can assign the values you receiving from the form to the variables, i just have shown a sample for understanding, if you print **kwargs you will get the values from the form, from that you can get the values and assign in dictionary

var1 = ' '

var2 = ' '

etc etc

data = { 'my_first_input' : ' var1' , 'my_second_input' : ' var2' }

Like that ? with empty variable at the beginning ?

or like that :

var_x_objet_consultation = kwargs.get('x_objet_consultation')

etc etc

data = { 'x_objet_consultation' : ' var_x_objet_consultation ' }

return request.env.cr['my table database']. create(data)
