annotate

问题 I'm trying to get a division between two annotate results in queryset. Impression is much larger than click, so I should get tenth decimal. def get_queryset(self): return googleData.objects.filter(account=self.account_name).\ values('date').\ annotate(Sum('click'), Sum('impression'), Sum('converted_click'), Sum('conversion_value'), Sum('cost'), Sum('conversion_value'), ctr_monthly= Sum('click')/Sum('impression')).\ order_by('-date') Trouble here: ctr_monthly= Sum('click')/Sum('impression'))

问题 I am trying to produce a graph and I am having some issues annotating it. My graph has a log scale on the x-axis, showing time. What I want to be able to do is keep the existing (but not predictable) numeric tick labels at 100 units, 1000 units, 10000 units, etc but also add custom tick labels to the x-axis that make it clear where more "human readable" time intervals occur---for instance I want to be able to label 'one week', 'one month', '6 months', etc. I can use matplotlib.pyplot.annotate

问题 I am aware that one is able to annotate a plot created by ggplot2 or even to combine large and small viewports, as is documented in the ggplot2-book. However, it seems that these only work in the actual plot-areas and not in the "final plot". For example I have a plot like this: Here we see ten panels showing a linear regression smoother applied to a binomial dataset, but that´s not the point. Now I want a summary (stored in a dataframe) in form of a text in the lower right of the plot, such

问题 I want to execute group by clause on MyUser table having CNT.Status exactly one the raw query would be like below. SELECT user_id from user_table GROUP BY user_id HAVING COUNT(status)=1 I tried various options using Django model API but its adding "id" too in group by clause. 回答1: It seems you are looking for filtering on annotations: qs = ( MyUser .objects .annotate(num_status=Count('status')) .filter(num_status__gt=1) ) Notice: I supose that status is a 1:N related model. 来源： https:/

问题 So I have a query with a few Q objects that are OR-ed together (to achieve a UNION), and I want to annotate each result with which Q object was a match. This is so when I go to display my query results, I can highlight which search term(s) were hits on each result. Here's the code that produces the resulting querySet: Gene.objects.filter(Q(EC__EC='3.2.1.4')|Q(Protein_Family__name__in=famList)|Q(Pfam__Pfam__in=pfams),Protein_length__gte=100, Distance_From_Contig_Upstream__gte=10, Distance_From

问题 I would like to display price SUM of all products related to particular room. Model : class Item(models.Model): product = models.CharField(max_length=150) quantity = models.DecimalField(max_digits=8, decimal_places=3) price = models.DecimalField(max_digits=7, decimal_places=2) purchase_date = models.DateField(null=True, blank=True) warranty = models.DecimalField(max_digits=4, decimal_places=1) comment = models.TextField() room = models.ForeignKey(RoomList) user = models.ForeignKey(User) class

问题 My goal is to annotate a plot made with ggplot2 by placing an equation in white space within the plot using the package latex2exp For example, given the equation: eqn <- "$\\textbf{Volume}(ml) = 0.035 \\cdot \\textbf{CSA}(mm^2) + 0.127 \\cdot \\textbf{age}(months) - 7.8$" Running the following code in R 3.5: library(ggplot2) library(latex2exp) ggplot(mpg, aes(x = displ, y = hwy)) + geom_point() + annotate("text", x = 4, y = 40, label=TeX(eqn), hjust=0, size = 5) My example code fails with the

问题 I need a component that I can install on my server that can be used in an ASP.NET Web Application to: Display word documents, PDF documents, images in the browser. Allow these documents to be annotated online and have those annotation saved for redisplay later. Thanks in advance. 回答1: Only a technology like Flash or Silverlight would be able to approach providing that functionality. The biggest benefits would be avoid cross-browser/platform issues and decent security. Also, I would be

问题 In order to build on this question here, we encountered another problem regarding aggregate annotations in the Django ORM. Because we need a join within our query it leads to this clumsy "extra" statement: Entry.objects.all() .extra(select={'week_year': "TO_CHAR(entry_addition.date, 'IW/YYYY')"}, where=["addition_id=entry_addition.id"], tables=['entry_addition']) .values('week_year') .annotate(Count('addition')) We created those the following two classes to get rid of the "extra" statement.

问题 Im trying to follow some online tutorial on annotating my models in rails. However, it seems all the tutorials are either talking about outdated annotation versions or incorrect installations its a mess. So far Ive tried the following 1) Added this in the Gemfile gem 'annotate', '2.4.0' 2) Then the command: bundle install 3) I then saw that the annotation gem was installed and showing up on the command bundle show 4) lastly in order to annotate my models I used the command bundle exec
