Difficulty in saving data in Crispy forms usung ModelForm in django
Saving data in django on a formn rendered by {{ form|crispy}} works fine but when I render the template using {{ form.ShowStatus|as_crispy_field}} nothing gets saved. Data is initially loaded into form with no problems, this is an update issue. Am I missing something? Django==3.0, django-crispy-forms==1.9.2, Bootstrap version 4.3.1, Python 3.8.5 Am I missing something? This works.... loads existing data into Show_form.html {% extends "fungi/base.html" %} {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4">New Filter</legend> {{ form|crispy }} </fieldset> <div class="form-group"> <button class="btn btn-primary" type="submit">Create filter</button> </div> </form> </div>loads {% endblock content %} Traceback for working code [24/Mar/2021 19:57:01] "GET /testform/show/3/ HTTP/1.1" 200 5065 [24/Mar/2021 19:57:06] "GET /testform/show/3/update/ HTTP/1.1" 200 11845 [24/Mar/2021 19:57:14] "POST /testform/show/3/update/ HTTP/1.1" 302 0 [24/Mar/2021 19:57:14] "GET /testform/show/3/ HTTP/1.1" 200 5062 This doesn't work.... loads existing data but doesn't save when submit button clicked Show_form.html {% extends "fungi/base.html" %} {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <div class="form-row"> <div class="form-group col-md-4 mb-0"> {{ form.ShowAll|as_crispy_field }} </div> <div class="form-group col-md-4 mb-0"> {{ form.ShowFungi|as_crispy_field}} </div> <div class="form-group col-md-4 mb-0"> {{ form.ShowHabitat|as_crispy_field}} </div> <div class="form-group col-md-4 mb-0"> {{ form.ShowStatus|as_crispy_field }} … -
How to use inner join on Subquery() Dajngo ORM?
I have to models class FirstModel(models.Model(): some_fields... class SecondModel(models.Model): date = models.DateTimeField() value = models.IntegerField() first_model = models.ForeignKey(to="FirstModel", on_delete=models.CASCADE) and I need query select sum(value) from second_model inner join ( select max(date) as max_date, id from second_model where date < NOW() group by id ) as subquery on date = max_date and id = subquery.id I think I can do it using Subquery Subquery(SecondModel.objects.values("first_model") .annotate(max_date=Max("date")) .filter(date__lt=Func(function="NOW"))) and F() expressions but it only can resolve model fields, not subquery Question is it possible to implement using django ORM only? also evaluate sum of values from secondModel for all values in first model by annotate this value? -
How to rewrite similar functions in Django
I have a python/django view function where it returns items from a model. I am creating a view with filters to see the data I want. Most of the time it only means changing one word in the function to get the filtered data I need. Is this best practice or should I be using some other programming construct? Here is an example of the function, in this case I have to create 3 functions/views and 3 urls to one for risk=high, risk=medium, risk=low, yada yada yada def Criticals(request): # YOU CAN NEGATE THE Q WITH THE TILDA#### items = ScanData.objects.filter(Q(Project_Assigned__icontains="Hooli") & (Q(Risk__icontains="Critical"))) numberIPs = items.count() Criticals = ScanData.objects.filter(Q(Risk="Critical") & (Q(Project_Assigned__icontains="Hooli"))) Highs = ScanData.objects.filter(Q(Risk="High") & (Q(Project_Assigned__icontains="Hooli"))) Mediums = ScanData.objects.filter(Q(Risk="Medium") & (Q(Project_Assigned__icontains="Hooli"))) Lows = ScanData.objects.filter(Q(Risk="Low") & (Q(Project_Assigned__icontains="Hooli"))) numberCriticals = Criticals.count() numberHighs = Highs.count() numberMediums = Mediums.count() numberLows = Lows.count() context = { 'items': items, 'header': 'The Hooli Project', 'numberIPs': numberIPs, 'numberCriticals': numberCriticals, 'numberHighs': numberHighs, 'numberMediums': numberMediums, 'numberLows': numberLows, } return render(request, 'index.html', context) -
Flatten Django Queryset that is using select_related() and full join
my goal is to union two querysets, however, they only match columns after the first queryset has been joined with it's foreign key table. Let me explain. Say I have three models like this: Models.py class Data(models.Model): name = models.TextField() extra_data = models.OneToOneField(Extra, on_delete=models.CASCADE) class Extra(models.Model): age = models.IntegerField() class FullData(models.Model): name = models.TextField() age = models.IntegerField() Then I am trying to do something like this: data = Data.objects.select_related() fullData = FullData.objects.all() queryset = data.union(fullData) This returns an error of: django.db.utils.OperationalError: SELECTs to the left and right of UNION do not have the same number of result columns The two issues here are: data does not get the columns if there is no related row in the Extra table The columns from select_related are only accessible by doing data.extra_data.age, meaning the left side of the union won't have the same number of columns. I want to utilize django, but it's not giving me the same results as a query like: SELECT * FROM Data LEFT JOIN Extra on Data.extra_data = Extra.id Please note I am using sqlite which is why the above query is written with a LEFT JOIN. Any thoughts on how I can get select_related() to return null … -

Python: asynchronically ssh to multiple servers and execute commands, then save result into database
I've searched extensively on Google and stackOverflow but cannot find relevant answer. So asking here. Hope you can kindly demo how to do it. My use case is as follows: User put in ip addresses in a django form field (e.g. 12.12.12.12, 13.13.13.13, 14.14.14.14) django take ips and ssh to those machines and execute predefined script if script runs successfully, then django saves the result to database django display each server's execution results (successful, failed) I can achieve the above function using sync methods, but the wait time is unbearably long.

Is using javascript to reassign parents an appropriate way to assign items into flex columns?
I am trying to show a bunch of images in a website, created in django, and I want to be organised into three columns. Since the images can be of different vertical dimensions, I have decided to create 3 divs, one for each column, whose display mode is flex as I do not want to enforce them being in a grid but let the images vary in height. The code below is my solution to this and does what I want it to but, as I'm very inexperienced when it comes to django+css+etc I am wondering if there is a nicer solution to this. Here is the css for the columns and their parent div .display_wrapper { grid-column: 2 / 2; display: grid; grid-template-columns: repeat(3,minmax(100px,400px)); text-align: center; justify-content: center; grid-column-gap: 10px; } .displaycol{display: flex; flex-direction: column; height: 100%;} I add the items to the html using a django for loop, as below {% for object in object_list %} <div class="displaycol" id="col1"> </div> <div class="displaycol" id="col2"> </div> <div class="displaycol" id="col3"> </div> <div class={% cycle "incol1" "incol2" "incol3" %} > <a class="link" href="{% url 'view_object' object_title=object.title %}"> <img class="object_image" src={{ object.photo1.url }} > <h3>{{object.title}}</h3> <p>paragraph</p> </a> </div> {% empty %} {% endfor … -
Using Snowpack to transpile Web Components and package dependencies
I am using Django to build a SSR website and using Django to serve static files. I also built some Web Components using lit-element and Typescript. I would like to avoid the complexity of Webpack and use Snowpack instead. Components are stored at /static/js/components. To use the components, I need to (1) transpile them to Javascript, (2) make available their dependencies (e.g. lit-element) and (3) move the transpired files as well as the _snowpack folder to Django's /static/ folder. Using just snowpack build does both but creates a build folder with a complete copy of the application. It is my understanding that buildOptions.out only moves the output folder (thereby overwriting static/ altogether if buildOptions.clean===true). I guess it would be possible to script the copying of the necessary files and delete the rest of the build folder immediately, but that strikes me as quite inelegant. Is there a configuration to only create _snowpack and the transpiled files to a specific directory? -

Django obj.save() creating duplicate profile instead of updating
I have created a rest API that i want to be able to use to update a users profile information, however instead of updating the profile it creates a new one for that user with the updated fields. so in signaly.py when the instance user is saved it also saves the users profile with instance.profile.save() which is meant to update the profile but instead creates another profile object for the user meaning they now have 2 profiles I have tried, in the serializer, to obtain the profile created first for the user and delete it but you cannot delete an obj that doesn't have a primary key. would appreciate it if anyone could help out, thanks models.py class Profile(TimestampedModel): user = models.OneToOneField( 'User', on_delete=models.CASCADE ) TEAM_CHOICES = ( [...] ) image = models.URLField(blank=True) location = models.CharField(max_length=50, blank=True) fav_team = models.PositiveSmallIntegerField(choices=TEAM_CHOICES, blank=True, null=True) points = models.PositiveIntegerField(default=0) def __str__(self): return self.user.username serializers.py class UserSerializer(serializers.ModelSerializer): password = serializers.CharField( max_length=128, min_length=8, write_only=True ) profile = ProfileSerializer(write_only=True) location = serializers.CharField(source='profile.location', read_only=True) image = serializers.CharField(source='profile.image', read_only=True) fav_team = serializers.CharField(source='profile.fav_team', read_only=True) points = serializers.CharField(source='profile.points', read_only=True) class Meta: model = User fields = ('email', 'username', 'password', 'token', 'profile', 'location', 'image', 'fav_team', 'points',) read_only_fields = ('token',) def update(self, instance, … -
Django Admin for Multi-Table Inheritance Models
I've got the following models for a user set up using multi-table inheritance: class MyBaseUser(AbstractBaseUser): # model fields.... class Meta: verbose_name_plural = 'Users' class SubUser(User): # model fields Now in terminal, everything seems to be working as expected, when creating a SubUser it returns a SubUser instance and creates a MyBaseUser in the db. If I query the MyBaseUser class for the id of the created SubUser it returns and I can do my_base_user_instance.subuser.<sub_user_field> - all behaving as I'd expect. How should I set up a ModelAdmin for the SubUser class though? I've got: @admin.register(SubUser) class SubUserAdmin(admin.ModelAdmin): # fields... but none of the SubUser instances are showing up, which I think makes sense given how the multi-table inheritance works, but how do I set up the admin to display/update the subclasses? I've not run into this before, thanks. -
How can I consolidate multiple entries in my data dictionary into only a single entry in my Django View class?
I am working on a Django site that allows a data dictionary to be generated using by analyzing an uploaded metadata set. Each metadata set contains a set of tables, and within those tables, each field and unique value associated with the field. Because some of the fields and/or values have meanings that are not always clear, a data dictionary can be generated which takes each field and/or value and allows users to enter in definition or explanation of field/value in question. It should also be noted here that there is additional information that users can add to each field in the Django site, which are: Is the field a person ID number? Should the field be ignored in the further analysis and data dictionary generation? Should the values in the fields be passed "as is" into further analysis? If the first two questions are marked as true, then the given field is excluded from the data dictionary generation and other analysis. If the last question is marked as true, then when that field is included in further analysis, its values are given without any additional transformation. However, I still want those fields to be included in the further analysis, … -

Error With Django URL When Passing Parameter
