PostgreSQL query slow, what's the issue?
I'm trying to store some measurement data into my postgresql db using Python Django. So far all good, i've made a docker container with django, and another one with the postgresql server. However, i am getting close to 2M rows in my measurement table, and queries start to get really slow, while i'm not really sure why, i'm not doing very intense queries. This query SELECT ••• FROM "measurement" WHERE "measurement"."device_id" = 26 ORDER BY "measurement"."measure_timestamp" DESC LIMIT 20 for example takes between 3 and 5 seconds to run, depending on which device i query. I would expect this to run a lot faster, since i'm not doing anything fancy. The measurement table id INTEGER measure_timestamp TIMESTAMP WITH TIMEZONE sensor_height INTEGER device_id INTEGER with indices on id and measure_timestamp. The server doesn't look too busy, even though it's only 512M memory, i have plenty left during queries. I configured the postgresql server with shared_buffers=256MB and work_mem=128MB. The total database is just under 100MB, so it should easily fit. If i run the query in PgAdmin, i'm seeing a lot of Block I/O, so i suspect it has to read from disk, which is obviously slow. Could anyone give me a … -
NotImplementedError: HiddenField.to_representation() must be implemented for field
I have a embedded document field in our django-mongoengine model like this. I am using django rest framework. Models are like this : class ProjectExpertsList: Name = StringField() class Project: Experts = ListField(EmbeddedDocumentField(ProjectExpertsList)) class ExProject: project = ReferenceField('Project') Serializers implemented is like this, where ProjectExpertsSerializer is Embedded Document Serializer. class ProjectSerializer(serializers.DocumentSerializer): preferred_experts = PreferredExpertsSerializer(ProjectExpertsList, many=True) Similarly I have ExProject Document Serializer. I have implemented document serializers for Project & Exproject with depth = 1 . But when i added this field this started throwing error. NotImplementedError: HiddenField.to_representation() must be implemented for field . If you do not need to support write operations you probably want to subclass ReadOnlyField instead. With the help of this link i have added serializers for embedded document. then also it's throwing the above error. -
can't update .po file in Django 1.8.8
I'm new to Django and now I am practicing Django Internationalization, intending to show my webpages in Chinese, however: Whatever changes i've made into the django.po file, and used compilemesseages to generate the .mo file, the pages still returned the previous translations, even if i delete the .po file and to generate a new one. Am I missing something? If so, please tell me, thank you :) This is my settings: LANGUAGE_CODE = 'zh-CN' TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True LANGUAGES = ( ('en', ('English')), ('zh_CN', ('中文简体')), ('zh-hant', ('中文繁體')), ) LOCALE_PATHS = ( os.path.join(BASE_DIR, 'locale'), ) also I've add the 'django.middleware.locale.LocaleMiddleware'into settings.py, just like this: MIDDLEWARE_CLASSES = ( 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.locale.LocaleMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.auth.middleware.SessionAuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'django.middleware.security.SecurityMiddleware', ) what i was test is this function in views.py: def test1_view(request): n = 2 weekdays = [_('Monday'), _('Tuesday'), _('Wednesday'), _('Thursday'), _('Friday'), _('Saturday'), _('Sunday')] return HttpResponse(weekdays[n]) the django.po file generated at /locale/zh_CN/LC_MESSAGES/django.po, and i'm sure i had delete the #,fuzzy: #: testdeploy/views.py:64 msgid "Monday" msgstr "一" #: testdeploy/views.py:64 msgid "Tuesday" msgstr "二" #: testdeploy/views.py:64 msgid "Wednesday" msgstr "三" #: testdeploy/views.py:64 msgid "Thursday" msgstr "四" #: testdeploy/views.py:64 msgid "Friday" msgstr "五" #: testdeploy/views.py:64 msgid "Saturday" msgstr "六" #: … -

Proper Django CSRF validation using fetch post request
I'm trying to use javascript's fetch library to make a form submission to my django application. However no matter what I do it still complains about CSRF validation. The docs on ajax mentions specifying a header which I have tried. I've also tried grabbing the token from the templatetag and adding it to the form data. Neither approach seems to work. Here is the basic code that includes both the form value and the header: let data = new FormData(); data.append('file', file);; data.append('fileName', file.name); // add form input from hidden input elsewhere on the page data.append('csrfmiddlewaretoken', $('#csrf-helper input[name="csrfmiddlewaretoken"]').attr('value')); let headers = new Headers(); // add header from cookie const csrftoken = Cookies.get('csrftoken'); headers.append('X-CSRFToken', csrftoken); fetch("/upload/", { method: 'POST', body: data, headers: headers, }) I'm able to get this working with jquery, but wanted to try using fetch. -
How to format Django setting file for flake8
I am kinda obsessed with formating my python code with flake8. However, I cannot find a good way to solve E501 (line too long x > 79 characters) in settings file of Django. First it was like this (4xE501): AUTH_PASSWORD_VALIDATORS = [ { 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, { 'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', }, { 'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, { 'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', }, ] and then I came up with this: AUTH_PASSWORD_VALIDATORS = [{ 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, { 'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', }, { 'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, { 'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', }, ] But still 'NAME':django.contrib.auth.password_validation.UserAttributeSimilarityValidator', is too long. Is there a way to format this or should I ignore this one? -

Handle form submission in bootstrap modal with ajax and class based views
i'm quite new using django and i've been stuck in this problem for several days. I have a form.Form in a bootstrap modal on my template with only 1 field (email_field) and basically i need to submit that form via ajax, check if that email address is registered in the database, then send an invitation to that email and close the modal. if the email is not registered show the form errors without closing the modal. I've tried with different examples but can find the solution either because the examples don't handle errors or the form is not inside a modal or not using class based views . I'm having 2 issues with my code: Not sure what to return in my view if the form is valid or invalid and how to handle errors in my js code to show them on the modal.(return tha form to render the errors or a JSON response??). After the first success submission is made the form cannot be used again.(The size of the submit button changes and if you click it return a error : CSRF token missing or incorrect) Form.py class CollaboratorForm(forms.Form): email_address = forms.EmailField(required=True,widget=forms.TextInput(attrs={'class': 'form-control focus-text-box', 'type': 'email', 'placeholder': 'Enter … -

Import a class into the urls.py in Django
In the last few weeks I've switched from developing an application that processes a simple XML file, then writes its contents to an Oracle DB (cx_Oracle) and outputs in HTML, to using a Django framework. The Django framework switch wasn't necessary, but since I have an opportunity to develop something by using Django, I thought why not as it is a new area for me and can't damage my CV. Anyway, I'm having issues with knowing what to write in my urls.py file when importing a Class from the views.py file. Here are the current contents: urls.py from myproj.views import Pymat_program pymatProgram = Pymat_program() urlpatterns = ( url(r'^pymat/$', pymatProgram.abc), ) views.py class Pymat_program: def abc(self, request): test = "<html><body>Random text.</body></html>" return HttpResponse(test) I've tried various permutations of using request, not using request, and also how the class is called in the url tuple, all to no avail. When I use a definition outside of the class (i.e. not in any class), then this is correctly displayed in HTML. -
