1.I am a Django learner. 2.I don't have much knowledge on jquery & Ajax. 3.I have two models ModelRegister and ModelGSPRequest in Models.py. 4.I have a requirement to populate 2 ManyToManyFields in ModelGSPRequest with the data based on selected drop down value,which is a Foreign Key to ModelRegister. 5.To accomplish this requirement ,i have written an Ajax function named load_model_details which triggers when there is a change in the model name drop down selection. Through this method i.e.,load_model_details i got all the model instances for the selected model & then i am passing it as a context to model_info_options.html to get the model number and OS Name details for the selected model. 6.Lets consider i have Model Register Model with below Table Data. 7.If user selectedmodel name:G5 modelNumber filled with H850,H860,O and P.[ its populatedwith both model number and os name data ] But it should contain only H850,H860 . Similarly os name filled with H850,H860,O and P but it should be only O and P. 8.So , Please suggest the proper way of accessing the response data in success method to display the correct data as per expected.
| ModelRegister | |||
| ModelName | ModelNo | OSName | chipset |
| G1 | G100 | O | qct |
| G2 | G110 | O | qct |
| G5 | H850 | O | qct |
| G5 | H860 | O | qct |
| G5 | H850 | P | qct |
| G5 | H860 | P | qct |
Below is my code.Models.py: --------- class ModelRegister(models.Model): 'This class is used to register the model'. model_name = models.CharField(max_length=128, verbose_name="ModelName") model_no = models.CharField(max_length=128, verbose_name="ModelNo") os_name = models.ForeignKey(OSName, on_delete=models.CASCADE, verbose_name="OSName",default=" ") class Meta: verbose_name_plural = "ModelRegisteredList" def __str__(self): return self.model_name class ModelGSPRequest(models.Model): 'This class is used to raise Model GSP request for a selected model using registered_model.' registered_model = models.ForeignKey(ModelRegister,on_delete=models.CASCADE, verbose_name="ModelName") registered_model_no = models.ManyToManyField(ModelNumber,default="") registered_model_os_name = models.ManyToManyField(OSNames,default="") model_gsp_requester = models.CharField("Model GSP Requester", max_length=128,default=" ") def __str__(self): return self.model_gsp_requester+str(self.pk)id_form-0-registered_model_no -> This is the id of the registered_model_no in my html ModelGSPRequest form. id_form-0-registered_model_os_name -> This is the id of the registered_model_os_name in my html ModelGSPRequest form. Model Register is a table with below data: ----------------------------------------- [![Model Register Table Data][1]][1] Consider Model Register table data as given below: ****Model Name Model No OSName**** --------------------------------------------------------- G5 H850 O G5 H860 O G5 H850 P G5 H860 P G7 G710 P G7 G712 P 1.ModelGSPRequest Model has a registered_model field, which is foreign key to ModelRegister to choose the modelname. 2.For example, when user selects model G5. I want to AutoFill registered_model_no with the values: H850 and H860 [registered_model_no: ManyToManyField ] and registered_model_os_name with the values of O and P [ registered_model_os_name:ManyToManyField ] With below code , when i select model name , both modelnumber and OSName details are updated . But registered_model_no should have only model number details and registered_model_os_name should have only OS Name details as shown in screen shot below. [![enter image description here][2]][2] Please suggest how to access model_info_options.html data in success method during ajax call.
Ajax.py:
=======
Below is the code snippet used get the model instances for the selected modeldef load_model_details(request): print("load model details") print("request method",request.method) modelname = request.GET.get("model")`enter code here` model_registered_instances = ModelRegister.objects.filter(model_name=modelname) return render(request, 'model_info_options.html', {'model_registered_instances':model_registered_instances})gspapp/templates/gspapp/model_info_options.html:
<!DOCTYPE html> <html lang="en"> {% for model in model_registered_instances %} <option value="{{ model.pk }}">{{ model.model_no }}</option> {% endfor %} {% for model in model_registered_instances %} <option value="{{ model.pk }}">{{ model.os_name }}</option> {% endfor %} </html>ModelGSPRequest.html:
`This is the html which is used to select the model name to auto fill the Registered Model Number and OS Name details based on selected model` `Below is the code snippet for Ajax call inside java script. ` <script type="text/javascript"> $("#id_form-0-registered_model").change(function () { var modelname = $(this).val(); // get the selected model from the HTML input $.ajax({ // initialize an AJAX request url: "load_model_details", data: { 'model': modelname // add the modelname to the GET parameters }, success: function (data) { // `data` is the return of the `load_model_details` view function [ i.e.,the data returned from model_info_options.html] $("#id_form-0-registered_model_no").html(data); // replace the contents of the city input with the data that came from the server $("#id_form-0-registered_model_os_name").html(data); } }); }); </script>Please suggest how to access model_info_options.html with the proper data in success method during ajax call & fill the registered model no and os name fields correctly for the selected model..
