How to use order_by on booleanfield using mongoengine

I want to order the result of my mongoengine call on two different fields.
Open. This has status True or False. I want this because I want to
display the open questions first
Opendate. Because I want to newest questions to show on top.
Combined this should create a list where I can see on top the open questions (ordered by creation date) and than the already closed questions, also ordered by creationdate.
The code I started with is:
To call the API:
questions = Questions.questions_of_user
To handle the call:
#queryset_manager
def questions_of_user(doc_cls, queryset):
return queryset.filter(questioner=current_user.id).order_by('-openDate')
My first suggestion was to just add 'status' to the order_by (maybe with or without + or - ) would do it. But so far no luck.
Than I tried to only order by the open field, because I thought I was just making an mistake combining the two. So I got this:
#queryset_manager
def questions_of_user(doc_cls, queryset):
return queryset.filter(questioner=current_user.id).order_by('-open')
That however did not work as well. I hope someone can help me out. Thanks in advance

More than one key can be passed in the order_by method of the queryset.
queryset.filter(questioner=current_user.id).order_by('-open', '-openDate')

Codenerix - Disable a dropdown field with foreign key using ng-readonly

Codenerix
Has anyone knows how to use correctly ng-readonly in a GenModelForm when coming from a sublist tab (GenList) who calls a GenCreateModal windows?
Structure is a master-detail, sublist tab has pk of master table and calls GenCreateModal with this pk argument of master table.
GenCreateModal receives pk argument in his asociated form (the mentioned GenModelForm) and can use it. The goal is to disable field with ng-disabled if pk argument of master table is filled. This way when create from another list of detail table without arguments, field can be filled with a value selecting it with the dropdown, and when coming from master table it cannot be modified and it will be assigned to master pk value.
I tried to do it that way:
First assign 'client' on GenCreateModal with:
def get_initial(self):
client = self.kwargs.get('pk', None)
if client:
self.kwargs['client'] = client
return self.kwargs
Then read it on the GenModelform with:
def __init__(self, *args, **kwargs):
super(DetailForm, self).__init__(*args, **kwargs)
if kwargs.get('initial', None) and kwargs['initial'].get('client', None):
self.fields['client'].widget.attrs[u'ng-readonly'] = 'true'
But it do not work with dropdown fields. Field can be modified.
Cause is that in templatetags_list.py of codenerix we have:
def inireadonly(attrs, i):
field = ngmodel(i)
return addattr(attrs, 'ng-readonly=readonly_{0}'.format(field))
This code set ng-readonly to "true readonly_client" instead of "true" when it comes with value "true" from GenModelForm, values are concatenated.
I found a workaround with:
self.fields['client'].widget.attrs[u'ng-readonly'] = 'true || '
this way the end value will be "true || readonly_client" that result on "true" as desired when evaluated, but I think it is not the proper way.
On my personal fork of django-codenerix I have changed the function to (functions is on two py files, should change both):
def inireadonly(attrs, i):
field = ngmodel(i)
if attrs.get('ng-readonly', None) is None:
attrs = addattr(attrs, 'ng-readonly=readonly_{0}'.format(field))
return attrs
This way it respects the value when it comes filled form GenModelForm, but I'm not sure about inconveniences and collateral effects. For example when want to concatenate conditions, with that change should read old value, concatenate manually and set new value. I think it should be a better way to do it and 'ng-readonly=readonly_{0}'.format(field) should have a functionality that I haven't discovered yet. Don't want to lose it when I discover it. So I revert the change and look for another solution.
Currently I'm using
self.fields['client'].widget.attrs[u'ng-disabled'] = 'true'
and it goes OK, I'm using this way and I have no problem now, but I'm curious about the way to use ng-readonly if I need it on the future. That's because with ng-readonly we can select text on fields with the mouse for example and can not select it with ng-disabled. In some cases it could be of interest.
Has anyone knows how to use ng-readonly in a correct way?
Has anyone knows the functionality of 'ng-readonly=readonly_{0}'.format(field)?

You can define an extra attribute to your fields in your forms. Add {'extra': ['ng-disabled=true']} in the field of your GenModelForm, inside your __groups__ method. Example:
def __groups__(self):
g = [
(_('Info'), 12,
['client', 6, {'extra': ['ng-disabled=true']}],
)
]
return g

You should use ng-disabled as you are doing. This is the way we do it in Django Codenerix Example # Gibhub (lines 41 and 42) and this is how it has been developed for StaticSelects (line 228) as well.

Querying DB for users when not all given parameters are filled

Sorry about the title being confusing it was hard to figure out how to word the question.
Currently I have a sqllite db with some users in it they have a first name, last name, dob, high school, and high school class. The db is connected to flask using sqlalchemy. What I'm wondering is for my search function I have 4 inputs and I want to have it so if an input isn't used then it won't be used in the search query. Say the person searches for the last name and high school I want it to search just using those parameters. I've tried doing this using a bunch of if statements but it seems messy there must be a better way. Below is the query that I use but it only works if all 4 are filled. Is there a better way than a bunch of if statements with different queries? I've looked around and haven't found anything.
userq=User.query.filter_by(first_name=fname_strip,last_name=lname_strip,hs_class=hs_class_strip).all()

You can try if/else statements like the following:
q = User.query.filter_by(first_name=first_name)
if lname_strip:
q = q.filter_by(last_name=lname_strip)
if hs_class_strip:
q= q.filter_by(hs_class=hs_class_strip)
# Execute the query
q.all()
Updated needs the q to be an assignment.

Okay so what I did was go through and make an if statement like you said but made them into different vars. Then check to see if they where none or not correct and if they were good then they queryied correctly if not then the queried for everything not null. Then changed them to be a set then did set intersection to see what was the same through all of them. Thank you for ionheart for helping me through this and providing the information this is the complete answer using his partial solution.
userf=set()
userl=set()
userc=set()
userh=set()
if fname_strip!='':
userf = User.query.filter_by(first_name=fname_strip).all()
print(userf)
else:
userf = User.query.filter(User.first_name.isnot(None))
if lname_strip!='':
userl = User.query.filter_by(last_name=lname_strip).all()
print(userl)
else:
userl = User.query.filter(User.last_name.isnot(None))
try:
int(hs_class_strip)
userc = User.query.filter_by(hs_class=hs_class_strip).all()
print(userc)
except:
userc = User.query.filter(User.hs_class.isnot(None))
if hs_strip!='':
userh = User.query.filter_by(hs=hs_strip).all()
print(userh)
else:
userh = User.query.filter(User.hs.isnot(None))
userq=[]
common=set(userf) & set(userl) & set(userc) & set(userh)
print(common)

If you pass the arguments to your search function as keyword arguments you can change the signature to accept kwargs and pass those on to the filter query
def search(**kwargs):
userq = User.query.filter_by(**kwargs).all()
This way any arguments you don't specify when calling search will not be passed onto the query, for example calling search(first_name='bob', last_name='fossil') will only add first name and surname arguments to the query

How to use Update query in Flask Peewee?

Hi I am using Flask Peewee and trying to update merchant_details model but it is not working.
Following is the error I am getting:
AttributeError: 'SelectQuery' object has no attribute 'update'
mdetails = merchant_details.filter(merchant_details.merchant_id==session['userid']).update(
merchant_name=request.form['merchantname'],
first_name=request.form['firstname'],
last_name=request.form['lastname'],
)
Please Help!

First, it looks like you are using pre-2.0 syntax (the filter method is now deprecated). I'd recommend looking at the docs for info on the latest version.
Typically, you do not "update a query". The two main ways of accomplishing this is are...
1.) Use a query to retrieve an object, then use the save() method to update the object. For example...
mdetails = MerchantDetails.select().where(MerchantDetails.id == 42).get()
mdetails.name = 'new name'
mdetails.save() # Will do the SQL update query.
2.) Use a SQL update statement...
q = MerchantDetails.update(name='new name')
.where(MerchantDetails.id == 42)
q.execute() # Will do the SQL update query.
Both of these, in essence, accomplish the same thing. The first will make two queries o the database (one to SELECT the record, another to UPDATE the record), while the second will only use one SQL call (to UPDATE the record).

I got the solution
mdetails = merchant_details.update(
merchant_name=request.form['merchantname'],
first_name=request.form['firstname'],
last_name=request.form['lastname'],
street_1=request.form['street1'],
street_2=request.form['street2'],
state=request.form['state'],
city=request.form['city'],
phone=request.form['phone'],
zipcode=request.form['zip'],
).where(merchant_details.merchant_id==session['userid'])
mdetails.execute()
Anyways Thanks Mark

I searched for this solution too and thanks to #Mark and #Rohit I changed my code (peeweee with PostgreSQL) and is working.
To add a small improve it seems the update will be executed even if you will not use the variable. For me is simpler and a cleaner code:
merchant_details.update(
merchant_name=request.form['merchantname'],
first_name=request.form['firstname'],
last_name=request.form['lastname'],
street_1=request.form['street1'],
street_2=request.form['street2'],
state=request.form['state'],
city=request.form['city'],
phone=request.form['phone'],
zipcode=request.form['zip'],
).where(merchant_details.merchant_id==session['userid']).execute()

Retrieve NodePointer.properties that was not inserted into DB yet

I'm using py2neo to insert some data into my neo4j db.
I create arrays of NodePointers and Relations and insert them with
for i in rels:
test_graph.create(i)
after the process.
During the creation of my arrays I would like to check if a specific NodePointer was already added to the array or not (don't want to create two NodePointers with same name).
Looking for a way to check a NodePointer properties, I've found this at py2neo documentation:
>>> alice.properties["name"]
'Alice'
but when I try to do:
def isThereAThisInHere(this, here):
for i in here:
if (i.properties["name"] == this):
return i
return False
mVar = isThereAThisInHere(defWord.wordVar[0],tempVar)
if (mVar == False):
mVar = Node("Variable",name=defWord.wordVar[0])
tempVar.append(mVar)
I get: 'NodePointer' object has no attribute 'labels'
Does anyone have a solution or suggestion for my problem? Thank you.

The problem was in the (mVar == False) comparison. Even though the error was raised at the .properties["name"] line.
