How can I retrieve the Aerodrone model name and code field values correctly?
I'm working on a Django project with two models, Aerodrone and Meteo. I defined a foreign key in the Meteo model to reference the Aerodrone model. However, the foreign key fields in the database are named aerodrone_id and code_aerodrone_id. I want to retrieve the values of the name and aerodrone_code fields from the Aerodrone model in the Meteo model. I wrote the admin part but the code_aerodrone field always retrieves the values of the name field instead of code. Help me solve this problem. Here is the code: class Aerodrone(models.Model): nom = models.CharField(verbose_name="Nom de l'aérodrone", max_length = 150, unique=True) code = models.CharField(verbose_name="Code de l'aérodrone", max_length = 50, unique=True) class Meta: verbose_name_plural = "Aérodromes" def str(self): return self.nom class Meteo(models.Model): id_message = models.ForeignKey(Idmessage,verbose_name="Id du message", on_delete=models.CASCADE) aerodrone = models.ForeignKey(Aerodrone,verbose_name="Nom de l'aérodromes", on_delete=models.CASCADE, to_field="nom", related_name = "meteo_aerodrone_nom") code_aerodrone = models.ForeignKey(Aerodrone,verbose_name="Code de l’aérodromes", on_delete=models.CASCADE, to_field="code", related_name = "meteo_aerodrone_code") id_station = models.CharField(verbose_name="Code de la station", max_length = 50) date_heure = models.DateTimeField(auto_now_add=True, verbose_name="Date et heure") direction_vent = models.CharField(verbose_name="Direction et la force du vent", max_length = 150) visibilite = models.CharField(verbose_name="Visibilité horizontale", max_length = 150) temps_significat = models.CharField(verbose_name="Temps significatif", max_length = 150) nuages_significatif = models.CharField(verbose_name="Nuages significatif", max_length = 150) temperature = models.CharField(verbose_name="Température de l’air sec et du … -

Quick hack to get Google Maps to look good on Mobile, works fine on Desktop for me
I have got a random google map location embedded onto a test location page. It appears fine and looks fine on Desktop. When I test on mobile.

Should I list the contestants according to the selected division?
I'm new to web development and I use the Django framework! I ask you to help or guide me on the right path. It is necessary to implement a selection of contestants according to the division selected from the drop-down list. The contestant model has a secondary key to the division model, the template implements the output of two forms: class divisionForm(ModelForm): # Подразделения class Meta: model = division fields = ['name_division'] widgets = { "name_division": Select(attrs={}), } class contestantForm(ModelForm): # Конкурсанты class Meta: model = contestant fields = ['name_contestant'] widgets = { "name_contestant": Select(attrs={}), } enter image description here As far as I understand, Django acts as a server and when the page loads, it returns the data processed in views.py how to implement the withdrawal of all contestants from the selected division in the template? already on the client side without POST and GET requests. Do you have a javascript example for interacting with Django on a similar topic? -
Concatenate 2 RawQuerySets Django
so i have each entity their and they are from legacy system, thats why i cannot perform migration. For example : Entity1 Blog Entity1 Entry Entity2 Blog Entity2 Entry There are 9 entities, means 18 tables So here is my view.py but i cannot do entity1_data.union(entity2_data). How can i merge these, so i can present it in 1 table? Ps: i would try union SQL, but theres too long. entity1_data = BlogModel.objects.using("bcdb").raw("SELECT blog.id as id, blog.name," + "entry.title, " + "entry.date " + "FROM [Entity1 Blog] as blog " + "INNER JOIN [Entity1 Entry] as entry " + "on blog.id = entry.blog_id") entity2_data = BlogModel.objects.using("bcdb").raw("SELECT blog.id as id, blog.name," + "entry.title, " + "entry.date " + "FROM [Entity2 Blog] as blog " + "INNER JOIN [Entity2 Entry] as entry " + "on blog.id = entry.blog_id") I hope i can do it dynamically using dict of tables name.

Question about using Group or Role in frontend application to restrict view
I am building an application that comprises a python backend using the django framework and a vue application on the frontend. I am using with success the authorization and permissions framework provided by django. I have created groups that possess a set of permissions and I have assigned users to them. Technically, after reading the docs, it is recommended to use groups to check for permissions and not roles. A problem arises when I need to serialize the user and send it to the frontend. What kind of information should I send to determine permissions on the frontend? Should I serialize all the groups the user belongs to with the respective permissions, or should I create a role field in my database to simplify things out (the roles are quite well defined) and just send that. What is the common solution or what would be reasonable? What kind of questions should be answered when approaching this problem? Thank you for your time. -
while we want to develop a travelling website using react how can we integrate a map api into our project
we need to provide a route map just like the google maps based on the user input that he/she wanted to visit the place, that should display the starting and destination locations of the user along with the type of transport that is available to visit that place. we tried to integrate the google maps API by generating a token but we are unable to integrate it in our project and we suppose that it is also not free of cost.so we need a map API and the process to integrate the API that can take the user input(location that the user wanted to visit). -

I have a problem merging navigation bar and footer html file together in my base html
I've been trying to figure out how to include the two templates in my base html and I found no success. I'm not certainly familiar with {% include %} and {% extends %} function and I believe I am not using it correctly to fix problem. With that being said, I added my navigation bar html using {% include %} on my base html along with my footer html also using with {% include %} as shown. The result is only the footer html appeared meanwhile the navigation bar html only resulted to a horizontal line beneath the search bar. {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>home</title> <link rel="stylesheet" href="/static/css/homestyle.css"> </head> <body> {% include 'webapp/templates/pages/navbar.html' %} <!-- navigation bar html --> {% include 'webapp/templates/pages/footer.html' %} <!-- footer html--> </body> </html> <!--navigation bar html --> {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>navbar</title> <link rel="stylesheet" href="/static/css/navbar.css">` ` </head> <body> <nav class="login_nav"> <p> login </p> </nav> <hr class="solid"> <nav> <img src="/static/images/user_logo.png"> <ul class="nav_links"> <li><a href="http://127.0.0.1:8000/artists/"> apple </a></li> <li><a href="http://127.0.0.1:8000/gallery/"> banana </a></li> <li><a href="http://127.0.0.1:8000/about/"> grape </a></li> </ul> </nav> <hr class="solid"> </body> </html> [`<!--footer html --> {% load static %} <!DOCTYPE html> <html lang="en"> <head> … -
How to combine selection and assignment in a single Django ORM query?
I'm trying to avoid race conditions when assigning objects from a pool to another object. meerkat_pool = Meerkat.objects.filter(customer=None) customer.meerkat = meerkat_pool.first() customer.save() Simultaneous requests result in the same meerkat being assigned to two different customers. Is there a way to run this as a single database query? F() expressions would be ideal if I could transform the QuerySet to a single value (e.g. customer.meerkat = F("first_meerkat_in_pool")).
