replace a string with condition in python
Question:
hi all i’m trying to create script that makes changes to my models file and i need it to change the textfield type to Bit1BooleanField when the field type is a guess
i tried this sultion but after replacing the first item everything is missed up
my models.py sample:
class BaseCase(models.Model):
base_case_name = models.CharField(primary_key=True, max_length=255)
version = models.CharField(max_length=255)
default = TextField(blank=True, null=True) # This field type is a guess.
class ConfigApiMatrix(models.Model):
bloc = models.CharField(primary_key=True, max_length=255)
page = models.CharField(max_length=255)
activate_model_api = models.TextField(blank=True, null=True) # This field type is a guess.
module_api_break_point = models.TextField(blank=True, null=True)
first_api_to_run_after_save = models.TextField(blank=True, null=True)
the solution i tried:
import re
with open('SFP/models.py', 'r') as myfile:
txt = myfile.read()
word = "Field(blank=True, null=True) # This field type is a guess."
for match in re.finditer(word, txt):
i=match.start()
txt = txt[:i-4-len(txt)] + "Bit1Boolean" + txt[i-len(txt):]
``

This should be a solution for you
search = 'TextField(blank=True, null=True) # This field type is a guess.'
replace = 'Bit1BooleanField(blank=True, null=True) # This field type is a guess.'
with open('SFP/models.py', "r") as f:
txt = f.read()
replaced_data = txt.replace(search, replace)
with open('SFP/models.py', "w") as f:
f.write(replaced_data)
