Unable to tweet more than 100 characters in tweepy?
I am using tweepy in my django project to tweet automatically. The following code do the same: access_token_secret = users.access_token['oauth_token_secret'] access_token = users.access_token['oauth_token'] # OAuth process, using the keys and tokens auth = tweepy.OAuthHandler(consumer_key, consumer_secret) auth.set_access_token(access_token, access_token_secret) # Creation of the actual interface, using authentication api = tweepy.API(auth) if request.method == 'POST': # create a form instance and populate it with data from the request: form = NameForm(request.POST) # check whether it's valid: if form.is_valid(): name = form.cleaned_data['your_name'] api.update_status(status=name); return HttpResponseRedirect('/home') This works fine if the length of status is less than 100, otherwise neither the tweet get posted, nor I get any error message. Any help? -

Error: cannot import name RemovedInDjango110Warning in django 1.9.5
So this code has been running for like a week now, today it is throwing this error. And this is not happening at the URL level, which many places seem to say. I am using celery, djcelery and Django 1.9.5. In my celery task, in one part where I am trying to connect to my DB, it is throwing this error. The strange part is when I run the code line by line in shell, it works. All this code runs inside a virtualenv being used by two projects which have exactly same requirements. to confirm, I just checked the django version in pip. It is 1.9.5 Please let me know if any extra info is required. -
django admin css on apache server
I need to solve the missing admin page css problem. I have tested almost all the solutions on the web with no luck! (I'm using django 1.8 on apache2.4) Here's what I've done so far: in setting.py I have: INSTALLED_APPS = [ ... django.contrib.staticfiles', ... ] STATIC_URL = '/static/' PROJECT_DIR = os.path.dirname(os.path.abspath(__file__)) STATIC_ROOT = os.path.join(PROJECT_DIR, 'static') and in etc/apache2/sites-available/000-default.conf I have: Alias /static /var/www/mysite/mysit/static <Directory /var/www/mysite/mysite/static> Require all granted </Directory> I also reloaded the apache. It seems that I'm doing something wrong since the django admin doesn't show the css. Any help would be appreciated. -
Software as a service in Django - many companies should be able to have the same users
Workflow: User in registration form gives his email, password and company name. The company with the same name is automatically creates during registration process(model Company). This user is automatically admin of the company(in User model I have role field). Company admin can invite candidates. In form gives candidate email, first and last name. Application sends an email with activation link to candidate. The candidate by clicking the link is transfered to the page with form where sets his password and is redirected to login page Candidate can log in and add new items to database(model Item) The problem is that many companies should be able to have the same user(the same email address). Currently application returns that email is already in use(in other company but it can't be like that). So this is something like Software as a Service. Any ideas how to solve this problem? -
Django / SQLite : Is there a way to see if someone is *currently* logged-in by checking db.sqlite3?
I'm using Django 1.10 with SQLite as my database back-end. I have a site running with nginx/uwsgi and the above configuration, which I'm constantly updating with new code. Each time I want to update the site code, I'm shutting down uwsgi, nginx, git pull ing the new version from my repo, then restarting uwsgi and nginx. While this works, in the sense that the site is updated with the new version of my code, the side-effect is that in the event that a user is currently logged in the site and working on something (which generally will result in modifying the db), the user's work will be interrupted. Worse still would be the case that the new version of my code contains migrations, which will change the db structure, with (unpredictable?) consequences on the user's on-going work. So the question is: is there a way, like a command-line script, to check db.sqlite3 and see if a user is currently logged-in, before deciding to shutdown uwsgi and nginx ? -

Django - ForeignKey : Is it possible get multiple kind of objects referencing itself?
models.py class BaseModel(TimeStampedModel): is_active = models.BooleanField(default=True) def deactivate(self): # Make all child objects is_active=False class ModelA(BaseModel) pass class ModelB(BaseModel): model_a = models.ForeignKey(ModelA) class ModelC(BaseModel): model_a = models.ForeignKey(ModelA) As you can see above, I want to make deactivate method for setting all childeren's is_active field as False. Someone might think of this way: def deactivate(self): # Make all child objects is_active=False b = ModelB.objects.filter(parent=self) c = ModelC.objects.filter(parent=self) for obj in b: obj.is_active = False obj.save() for obj in c: obj.is_active = False obj.save() But it only works for ModelA which ModelB, ModelC are referencing, not available for all models. I want to make it general method so that I can use it in any models: all_model_objects = ModelsReferencingMe.objects.filter(parent=self) Is there any way to implement this? -
Queryset is evaluated when sliced?
In django queryset doc(https://docs.djangoproject.com/en/1.10/ref/models/querysets/), it says "Internally, a QuerySet can be constructed, filtered, sliced, and generally passed around without actually hitting the database. No database activity actually occurs until you do something to evaluate the queryset." And then, it says "You can evaluate a QuerySet in the following ways: Iteration / Slicing / . . ." . So, my question is "whether Queryset is evaluated when sliced" . -

Properties Format on Geojson to MongoDB/Mongoengine
I would like to find a solution on what DataField I should give to a geojson with a properties column. Currently a geojson format below would not have any issues since it it would only need the StringField() and PointField(). A geojson format looks like this: { name : "Timmy's Taco Truck", loc : { type : "Point", coordinates : [ 37.7577 , -122.4376 ] } } However for a geojson with this format: { "type" : "Feature", "id" : "ID80001", "geometry":{"type": "LineString", "coordinates":[[122.332,14.241],[125.332,13.532]]}, "properties":{ "name":"Dummy Name", "color":"#000000" } } Using a model like the one below: from mongoengine import * from colorful.fields import RGBColorField class Geometry(Document): type = StringField() id = StringField() geometry = LineStringField() name = StringField() color= RGBColorField() ***OR*** properties = ??? If I use EmbeddedDocumentField and create a separate properties field it would result to "properties": [{"name": "Dummy Name","color": "#000000"}] not: "properties": {"name": "Dummy Name","color": "#000000"} How can I preserve the geojson format in the models? -

Django : combine variable and HTML id in template
I'm looking for a way to "concatene" a django object list (get via the get_queryset in the views.py) with a Javascript variable. then concatene them to a field of a model object. My model is a blog post, and contains the post_title field (a charfield). In my index.html, I have a pager button with id="1" or id="2" corresponding to the index of the page and a onClick="displayPostContentOnPageButtonCliked(this.id)" attribute. My index.html retrieve all post objects in a context_object_name called all_post_by_date. In my index.html, I want to display on alert dialog the post title corresponding to the button clicked, something like: <script> function displayPostContentOnPageButtonCliked(page_button_clicked_id){ var all_posts_by_date = "{{all_posts_by_date.page_button_clicked_id.post_title}}"; alert(all_posts_by_date); } </script> But this doesn't work. I tried to add filter or create my own filter (called get_index, but only manage to get like: all_posts_by_date|get_index:page_button_clicked_id and not be able to combine the .post_title part. My question is: how to get {{all_posts_by_date.page_button_clicked_id.post_title}} to work, and alert "Title of post 3" when the button 3 is clicked ? Thank u ! -

Returning items as they come in Python
I am not quite sure I am using the correct terminology but I would like to have access to items being returned by my function before the function finishes. For example, I am working on a Django project where I have a function that scrapes a cooking website, and returns what recipes you can cook based on the ingredients that you have. The function works as expected but it takes a very long time. I would like to present users with the recipes that they can cook as they are found, instead of them having to wait for the entire function to run and thus the webpage to load. I've pasted the relevant code below. Any help would be greatly appreciated. def give_recipe_from_ingredients(pantry_items): for link in get_recipe_links(): current_ingredient_list = [] can_cook = True grab_from = link grab_page = urllib.request.urlopen(grab_from) grab_soup = BeautifulSoup(grab_page, 'html.parser') rec_title = grab_soup.find('h2', attrs={'entry-title'}) title = rec_title.text.strip() for ingredient in grab_soup.find_all('span', itemprop="name"): ingredient_strip = ingredient.text.strip() current_ingredient_list.append(ingredient_strip) for item in pantry_items: for ingredient_in in current_ingredient_list: if str(item) in ingredient_in: if title not in recipes_you_can_cook: recipes_you_can_cook.append(title) return recipes_you_can_cook
