weasyprint

问题 I have made a flask application which generates .pdf from html with weasyprint and send it as attachment. But apparently bootstrap 4 css is not applied. I can't find a solution. It is working well with pdfkit but I need weasyprint, since pythonanywhere.com does not support pdfkit. I have tried linking bootstrap, using bootstrap css as file in my html, but there was no difference. This is my python part, which generates and sends pdf. @app.route('/pdf_send', methods=('GET', 'POST')) @login

问题 I've been using Weasyprint for pdf generation successfully, until I reach a certain size, a common use case of my app, where the pdf generation takes so long (more than 10s) that it breaks the connectivity with the browser, and the download is impossible. I suppose I must stream the file creation and return a django StreamingHttpResponse (agree ?). I wouldn't pre-process the pdf because it is formed from baskets with items users frequently add or delete. But how can I stream the file creation

问题 I recently updated my OS on my mac to El Capitan and since then have been running into issues trying to run WeasyPrint. I have updated macports, uninstalled and reinstalled all of the macport dependencies. I've also uninstalled and reinstalled WeasyPrint via pip with no issues, but still it doesn't run. I also have the export DYLD_FALLBACK_LIBRARY_PATH="/opt/local/lib" in my ~/.profile which helped solve the import errors and allowed WeasyPrint to run before I had El Capitan installed. When i

问题 I can't seem to get WeasyPrint to work on Windows with Python 3.4 or 3.5. Has anyone been able to do this? There aren't forums at weasyprint.org and the IRC channel is dead. I've been able to install using both Python 3.4.3 and 3.5.1. I've followed the guideline found here [1]. I've also made note that WeasyPrint's site claims it should work with Python 2.6+ or 3.1+. When I install for Python 3.4.3 and open the Python shell and simply 'import weasyprint' I get this: C:\Python34>python Python

问题 I have a project started with Cookiecutter Django and I'm currently adding WeasyPrint to serve some views as PDF files. This is working fine on development. Cookiecutter Django is using Caddy as the HTTP server. I'm having errors on production due I can't access to files through its absolute URL from inside the Django docker instance. From inside the Django docker instance, this does not work: $ curl https://myowndomain.com curl: (7) Failed to connect to myowndomain.com port 443: Connection

问题 I am trying to output PDF on Django using the Weasyprint library, but the images don't appear on the generated PDF. I have tried both relative and static URLs for the images, but even the static URL doesn't show the image. When opening the HTML itself on chrome, the images do show. Here is my pdf generation view in the views.py file: def pdf_generation(request, some_slug) stud = Student.objects.get(some_slug=some_slug) studid = stud.some_slug context = {'studid':studid} html_string = render

问题 I want to generate reports using WeasyPrint in Django. But I don't know how to integrate the css (specifically the bootstrap css file). I am able to see the generated html. But I get a warning when I add this line to my template- <link href="/static/css/bootstrap.min.css" rel="stylesheet"/> The warning is - Relative URI reference without a base URI: at line None I would like to know how to send the base URI to the template. Any help would be appreciated. 回答1: Answering my own question. Yeah

问题 I'm getting OSError: dlopen() failed to load a library: cairo / cairo-2 when trying to execute Django after a new install. Using Windows. I'm using Weasyprint, seems to be related to that one, according to the full trace: Unhandled exception in thread started by <function wrapper at 0x03F605B0> Traceback (most recent call last): File "C:\my-venv\lib\site-packages\django\utils\autoreload.py", line 226, in wrapper fn(*args, **kwargs) File "C:\my-venv\lib\site-packages\django\core\management
