I am trying to update a handful of fields if the record has been marked as deleted. When I debug, I can see that the values are being assigned in the view, but not being updated in the DB. I'm not sure what I'm missing.
views.py
contact_formset = ContactFormSet(request.POST, prefix='contact')
for contact in contact_formset.deleted_forms:
contact = contact.cleaned_data
print(contact)
instance = contact['id_cnt']
contact_id = instance.id_cnt
contact_object = get_object_or_404(AppContactCnt, id_cnt=contact_id)
contact_object.deleted_cnt = True
contact_object.date_deleted_cnt = '2020-11-23'
contact_object.deleted_by_cnt = 'adeacon'
contact_object.save()
Included the delete code with the edit code. Seemed to do the trick:
if '_edit_contact_formset' in request.POST:
contact_formset = ContactFormSet(request.POST, prefix='contact')
for contact_form in contact_formset:
if contact_form.is_valid() and contact_form.has_changed():
contact_data = contact_form.cleaned_data
# print(contact_data)
customer_obj = get_object_or_404(AppCustomerCst, id_cst=id)
contact_form.instance.idcst_cnt = customer_obj
contact_form.instance.idtrp_cnt = '-1'
if contact_data['DELETE'] is True:
print('delete me')
contact_form.instance.deleted_cnt = True
contact_form.instance.date_deleted_cnt = '2020-11-23'
contact_form.instance.deleted_by_cnt = 'adeacon'
messages.info(request, 'Contact deleted successfully')
contact_form.save()
formset = ContactFormSet(
queryset=AppContactCnt.objects.filter(idcst_cnt=id).exclude(deleted_cnt=True).select_related('idctp_cnt'),
prefix='contact')
if contact_data['DELETE'] is not True:
messages.info(request, 'Contacts updated successfully!')

I'm a new Django programmer. I write a API call with rest_framework in Django. when call this API, my program connect to KUCOIN and get list of all cryptocurrency. I want save symbol and name this cryptocurrencies in database. For save data to database, I use 'for loop' and in every for loop iteration, I query to database and save data. my code :
for currencie in currencies:
name = currencie['name']
symbol = currencie['symbol']
active = (False, True)[symbol.endswith('USDT')]
oms = 'kucoin'
try:
obj = Instrument.objects.get(symbol=symbol, oms=oms)
setattr(obj, 'name', name)
setattr(obj, 'active', active)
obj.save()
except Instrument.DoesNotExist:
obj = Instrument(name=name, symbol=symbol,
active=active, oms=oms)
obj.save()
query to database in every for loop iteration have problem ,How can I solve this problem?
Exist any way in Django to save data in database in with one query.
All my code:
class getKucoinInstrument(APIView):
def post(self, request):
try:
person = Client.objects.filter(data_provider=True).first()
person_data = ClientSerializer(person, many=False).data
api_key = person_data['api_key']
api_secret = person_data['secret_key']
api_passphrase = person_data['api_passphrase']
client = kucoin_client(api_key, api_secret, api_passphrase)
currencies = client.get_symbols()
for currencie in currencies:
name = currencie['name']
symbol = currencie['symbol']
active = (False, True)[symbol.endswith('USDT')]
oms = 'kucoin'
try:
obj = Instrument.objects.get(symbol=symbol, oms=oms)
setattr(obj, 'name', name)
setattr(obj, 'active', active)
obj.save()
except Instrument.DoesNotExist:
obj = Instrument(name=name, symbol=symbol,
active=active, oms=oms)
obj.save()
return Response({'response': 'Instruments get from kucoin'}, status=status.HTTP_200_OK)
except Exception as e:
print(e)
return Response({'response': 'Internal server error'}, status=status.HTTP_500_INTERNAL_SERVER_ERROR)
Thank you for you help.
Yes! Take a look at bulk_create() documentation. https://docs.djangoproject.com/en/4.0/ref/models/querysets/#bulk-create
If you have a db that supports ignore_conflicts parameter (all do, except Oracle), you can do this:
new_currencies = []
for currencie in currencies:
name = currencie['name']
symbol = currencie['symbol']
active = (False, True)[symbol.endswith('USDT')]
oms = 'kucoin'
new_currencies.append(Instrument(name=name, symbol=symbol,
active=active, oms=oms))
Instrument.objects.bulk_create(new_currencies, ignore_conflicts=True)
1-liner:
Instrument.objects.bulk_create(
[
Instrument(
name=currencie['name'], symbol=currencie['symbol'],
active=currencie['symbol'].endswith('USDT'), oms='kucoin'
)
for currencie in currencies
],
ignore_conflicts=True
)
Our Oracle database is upgraded to a new server, so it has a new server name. Most of our published workbooks on Tableau Server are connecting to this Oracle database. The username and password remains the same, but the server address is changed. I used the following Python code. It can identify the right workbook that needs server address update, however it produces an error: 'PW Update Failed with error:

How to fix the code?
you have to update the workbooks.
server.workbooks.update_connection(wb, connection)
I ran into the same problem and I'm hoping my solution fixes yours. I created a "helper" class that has one attribute called "id":
class datasource_id:
def __init__(self, id):
self.id = id
I put the class at the top of my code. Then I replaced the lines:
if overwrite_credentials:
connection.embed_password = True
connection.username = replace_username
connection.password = replace_pw
server.datasources.update_connection(wb, connection)
with the code below in both places:
if overwrite_credentials:
connection.embed_password = True
connection.username = replace_username
connection.password = replace_pw
d1 = datasource_id(wb.connections[item].datasource_id)
server.datasources.update_connection(d1, connection)
The reason this work is because the method .update_connections is using the argument in the id position of the "wb" as the datasource_id which isn't correct because the id position of the "wb" variable is the id of the workbook
i am getting fields data from xls file and creating product
everything work fine except one2many field of variant in product.template
how can i achieve this.
here is my code.
main_product = self.env["product.template"].create(product_data)
attribute_ids = self.env["product.attribute"].search([])
attrib_id_set = set(ids.name for ids in attribute_ids)
product_attrib_ids = sheet.cell(suits, 13).value.split(",")
attrib_id_list = []; exist_attribute_list = []
for name in product_attrib_ids:
if name not in attrib_id_set:
attrib_id = self.env["product.attribute"].create({'name':name})
attrib_id_list.append(attrib_id)
else:
exist_attribute = self.env["product.attribute"].search([('name','=',name)])
exist_attribute_list.append(exist_attribute)
union_list = list(set(attrib_id_list).union(exist_attribute_list))
exist_attribute_values = self.env["product.attribute.value"].search([])
exist_attrib_val_list = [attrib_name.name for attrib_name in exist_attribute_values]
product_attrib_id_values = sheet.cell(suits, 14).value.split(",")
for value in product_attrib_id_values:
if value not in exist_attrib_val_list:
for ids in union_list:
attrib_value_id = self.env["product.attribute.value"].create({
'attribute_id':ids.id,
'name':value
})
main_product.write({
'attribute_line_ids':[(0,0,{
'attribute_id':ids.id, 'value_ids':(4,attrib_value_id.id)
})]
})
product_data is my dictionary for fields like name,sale_ok,type,catag_id etc.
this works, product is created, attribute_id and attribute values even works
but i can not write one2many of variant in product.template.
--EDIT--
values_lst=[]
for value in product_attrib_id_values:
if value not in exist_attrib_val_list:
for ids in union_list:
attrib_value_id = self.env["product.attribute.value"].create({
'attribute_id':ids.id,
'name':value
})
else:
for ids in exist_attribute_values:
if value == ids.name:
attrib_value_id =self.env["product.attribute.value"].browse(ids.id)
if attrib_value_id not in values_lst:
values_lst.append(attrib_value_id)
I have the following form in my flask app. I'd like to ensure that the input value is actually an integer and also if the value entered in token > k here k can be some number it spits an error message to the screen. The IntegerField doesn't seem to enforce integer values, e.g., if the user enters 2.3 it passes that to my function which fails because it expects an integer.
Can this type of error message happen in the form or do I need to program that inside my flask app once the value is passed from the form to the server?
class Form(FlaskForm):
token = IntegerField('Token Size', [DataRequired()], default = 2)
submit = SubmitField('Submit')
EDIT
Per the comment below, updating this with my revised Form and the route
class Form(FlaskForm):
token = IntegerField('Token Size', validators=[DataRequired(), NumberRange(min=1, max=10, message='Something')], default = 2)
ngram_method = SelectField('Method', [DataRequired()],
choices=[('sliding', 'Sliding Window Method'),
('adjacent', 'Adjacent Text Method')])
rem_stop = BooleanField('Remove Stop Words', render_kw={'checked': True})
rem_punc = BooleanField('Remove Punctuation', default = True)
text2use = SelectField('Text To Use for Word Tree', [DataRequired()],
choices=[('clean', 'Clean/Processed Text'),
('original', 'Original Text String')])
pivot_word = TextField('Pivot Word for Word Tree', [DataRequired()])
submit = SubmitField('Submit')
And the route in which the form is used
#word_analyzer.route('/text', methods=('GET', 'POST'))
def text_analysis():
form = Form()
result = '<table></table>'
ngrams = '<table></table>'
orig_text = '<table></table>'
text = ""
if request.method == 'POST':
tmp_filename = tempfile.gettempdir()+'\\input.txt'
if request.files:
txt_upload = request.files.get('text_file')
if txt_upload:
f = request.files['text_file']
f.save(tmp_filename)
if os.path.exists(tmp_filename):
file = open(tmp_filename, 'r', encoding="utf8")
theText = [line.rstrip('\n') for line in file]
theText = str(theText)
token_size = form.token.data
stops = form.rem_stop.data
punc = form.rem_punc.data
ngram_method = form.ngram_method.data
text_result = text_analyzer(theText, token_size = token_size, remove_stop = stops, remove_punctuation = punc, method = ngram_method)
result = pd.DataFrame.from_dict(text_result, orient='index', columns = ['Results'])[:-3].to_html(classes='table table-striped table-hover', header = "true", justify = "center")
ngrams = pd.DataFrame.from_dict(text_result['ngrams'], orient='index', columns = ['Frequency']).to_html(classes='table table-striped table-hover', header = "true", justify = "center")
if form.pivot_word.data == None:
top_word = json.dumps(text_result['Top Word'])
else:
top_word = json.dumps(form.pivot_word.data)
if form.text2use.data == 'original':
text = json.dumps(text_result['original_text'])
else:
text = json.dumps(text_result['clean_text'])
if form.validate_on_submit():
return render_template('text.html', results = [result], ngrams = [ngrams], form = form, text=text, top_word = top_word)
return render_template('text.html', form = form, results = [result],ngrams = [ngrams], text=text, top_word='')
Use the NumberRange validator from wtforms.validators.NumberRange. You can pass an optional Min and Max value along with the error message. More info here
Update
# Form Class
class Form(FlaskForm):
token = FloatField('Token Size', validators=[DataRequired(), NumberRange(min=1, max=10, message='Something')])
# Route
if form.validate_on_submit():
print(form.name.data)
Here is an example that should work, make sure your form class field looks similar and also that in your route you use form.validate_on_submit():.

You can use compute or default function to load value in to field or you can also pass value while creating record
default function example:
name = fields.Char(
string='Name',
default=lambda self: self._get_default_name(),
)
#api.model
def _get_default_name(self):
return "test"
Refer this link for computed fields
