Pytesseract - using .traineddata file on hosted server (Heroku)
I have a Vue, Django integrated project. I hosted the Vue project on Netlify and the Django project on Heroku. A python script (integrated into Heroku) is called on certain buttons which extract data and posts this to the Django API to be viewed on the frontend. I have trained a font type for my pytesseract OCR script. However, when i run it on Heroku, it seems like i can only use the 'eng' (normal font) as 'language' for my pytesseract image_to_string function. If I have the .traineddata file of the font type that I want to use, how can I use this file within the pytesseract functions? I can call the individual file, but I need the right TESSDATA_PREFIX as well. Does someone know how to deal with this? Thanks! -
Vue development version works but production doesn't (Vue CLI + Django)
I have build a site using Django and Vue+Vuetify, with Django running the backend and Vue the front end. I have been using Vue CLI to compile by .vue files. However, now that I am preparing to move the code to production version, I have run into following issue: Vue app created by vue-cli-service build does not work. When run in development mode with vue-cli-service build --mode development it all works fine, but the build version doesn't work. The JavaScript console doesn't give any errors. Almost nothing renders and what little renders doesn't seem to have styling included. However, I can see that axios calls do work, and using inspector shows that various elements are added to the body, they simply do not render. However, looking at my package.json I can't see any obvious errors. { "name": "vueapp", "version": "0.1.0", "private": true, "scripts": { "serve": "vue-cli-service serve", "build": "vue-cli-service build", "build-dev": "vue-cli-service build --mode development", "lint": "vue-cli-service lint" }, "dependencies": { "axios": "^0.21.1", "core-js": "^3.6.5", "vue": "^2.6.11", "vue-router": "^3.2.0", "vuetify": "^2.4.0" }, "devDependencies": { "@mdi/font": "^5.9.55", "@vue/cli-plugin-babel": "~4.5.0", "@vue/cli-plugin-eslint": "~4.5.0", "@vue/cli-plugin-router": "~4.5.0", "@vue/cli-service": "~4.5.0", "babel-eslint": "^10.1.0", "eslint": "^6.7.2", "eslint-plugin-vue": "^6.2.2", "material-design-icons-iconfont": "^6.1.0", "sass": "~1.32.0", "sass-loader": "^10.0.0", "vue-cli-plugin-vuetify": "~2.4.1", "vue-template-compiler": "^2.6.11", … -
Tooltip ignores bootstrap5 css
I am having problems using bootstrap 5 tooltips in my webapp. My django template works as follows: {% block css %} <!-- Bootstrap CSS --> <link rel="stylesheet" href="{% static 'css/bootstrap.min.css' %}"> <link rel="stylesheet" href="{% static 'css/base.css' %}"> <!-- Bootstrap CSS for Tabulator --> <link rel="stylesheet" href="{% static 'css/tabulator_bootstrap4.min.css' %}"> {% endblock %} ... {% block javascript %} <!-- jQuery --> <script src="{% static 'js/jquery-3.6.0.min.js' %}"></script> <!-- tabulator --> <script src="{% static 'js/tabulator.min.js' %}"></script> <!-- Bootstrap JavaScript --> <script src="{% static 'js/bootstrap.bundle.min.js' %}"></script> <!-- bootstrap select picker --> <script src="{% static 'js/bootstrap-select.js' %}"></script> <link rel="stylesheet" href="{% static 'css/bootstrap-select.min.css' %}"></script> <!-- font awesome --> <script src="{% static 'fontawesome_free/js/all.min.js' %}"></script> {% endblock javascript %} In my html I use this code: var tooltipTriggerList = [].slice.call(document.querySelectorAll('[data-bs-toggle="tooltip"]')) var tooltipList = tooltipTriggerList.map(function (tooltipTriggerEl) { console.log("added a tooltip"); return new bootstrap.Tooltip(tooltipTriggerEl) for this button, which shows just an ordinary tooltip: `<button type = button class="btn btn-sm btn-primary" data-bs-toggle="tooltip" data-bs-placement="top" title="${row.tooltip}"> <i class="fas fa-print"></i> </button>`; I can see the added a tooltip message never shows ... why? -

Django Logging Emails not Arriving while other Emails do
I'm currently using this configuration to receive logging emails from my development as well as my production servers. ADMINS = [('Test1', 'somename@example.com'), ('Test2', 'someothername@example.com')] SERVER_EMAIL = "correctsender@example.com" LOGGING = { 'version': 1, 'handlers': { 'mail_admins': { 'level': 'ERROR', 'class': 'django.utils.log.AdminEmailHandler', 'include_html': True, }, }, 'loggers': { 'django.request': { 'handlers': ['mail_admins'], 'level': 'ERROR', 'propagate': False, }, } } The email is then sent with the following configuration for SMTP. EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_HOST_USER = 'correctsender@example.com' EMAIL_HOST_PASSWORD = 'thepassword' # normally loaded from environment EMAIL_PORT = 587 EMAIL_USE_TLS = True DEFAULT_FROM_EMAIL = 'correctsender@example.com' I have enabled "Less secure Apps" in Gmail. For a few days now, we suspected that error logging was broken. Today we confirmed that the Mails sent via AdminEmailHandler were not arriving, while all other Mails send via the ordinary mail pipeline (no matter if from celery workers or directly from the server) were. Test with other backends showed that the Mail was sent by django. A quick test with smtplib showed that login was not blocked. How can it be that certain mails are accepted by Gmail while others, only differing in content, are not? Also, is there a place where rejected Emails are kept … -

Django Docker deployment
Having never made a website or used Docker before, I've built a Django application with MySQL inside Docker and am finally ready for deployment, but completely overlooked that a web server was necessary. I've been quite stuck getting it to work and was wondering what approach others used. Is Apache or Nginx easier to set up, and does it need to be set up inside the Dockerfile and docker-compose.yml file, or can it be set up externally? I haven't been able to find much relevant information for this, so any advice or links would be appreciated. -

Is editable=False required?
I am developing a model, the only actions that can be performed on an instance of it are view and delete. Moreover, all these actions must take place in the StackedInline, which is bound to the ModelAdmin class of another model. Model example: class IncludingModel(models.Model): ... class ReadAndDeleteOnlyModel(models.Model): field1 = models.TextField(verbose_name="First field", editable=False) field2 = models.TextField(verbose_name="Second field", editable=False) including_model_instance = models.ForeignKey(IncludingModel, related_name="read_and_delete_only_instances") Admin example class ReadAndDeleteOnlyModelInline(admin.StackedInline): model = ReadAndDeleteOnlyModel readonly_fields = ("field1", "field2") def has_add_permission(self, request, obj): return False @admin.register(IncludingModel) class IncludingModelAdmin(admin.ModelAdmin) inlines = (ReadAndDeleteOnlyModelInline,) Interaction with ReadAndDeleteOnlyModel instances occurs only in IncludingModelAdmin. After removing editable = False, my fields are still read-only due to the fact that I specified them in readonly_fields. This begs the question, is editable = False needed in my case? -

Override Wagtail delete confirmation message
I would like to override the delete message (to make it more informative, like “if you delete, you will lose 5 items belong to your account”). My idea is whenever someone deletes my “Member”, it will also delete all the items belong to that member, and the confirmation message should provide more information. I find that the confirmation message comes from a function named “confirmation_message” in wagtail.contrib.modeladmin.views, at DeleteView class. This function will provide the message for Wagtail delete's template. This is my Member class: class Member(ClusterableModel): user = models.OneToOneField(User, on_delete=models.CASCADE) email_confirmed = models.BooleanField(default=False) phone = PhoneNumberField(blank=True) phone_2 = PhoneNumberField(blank=True) inside_scoop = models.TextField(blank=True) lifetime_member = models.BooleanField(default=False) activation_date = models.DateField(null=True, blank=True, default=timezone.now) deactivation_date = models.DateField(null=True, blank=True) points_balance = models.IntegerField(default=0) favorite_properties = models.ManyToManyField( PropertyPage, blank=True, related_name="favorite_properties" ) base_form_class = MemberFormAdmin def delete(self: object, *args: list, **kwargs: dict) -> None: PropertyPage.objects.filter(owner=self.user).delete() self.user.delete() return super(self.__class__, self).delete(*args, **kwargs) This is the default confirmation message that comes from Wagtail: this lies in wagtail -> contrib -> modeladmin -> views.py And this is the delete template: this lies in wagtail -> contrib -> modeladmin -> templates → modeladmin → delete.html This is the message for staff in admin portal: Please help me with this case, thank you. -
