Python-docx set the text direction RTL

Question

I am trying to create a docunent with RTL (Right-To-Left) text direction

def printExam():

  #get the exam questions 

  rows = db(db.exam_questions.exam == request.vars.exam).select()

  # create the documnet
  document = Document()
  document.add_heading(u"أختبار", 0)

  #for row in rows:
  row = rows[0] 
  run = document.add_paragraph().add_run(str(row.question.questionText).decode( "utf-8" ))
  font = run.font
  font.rtl = True

I got the following exception:

Traceback (most recent call last):
  File "C:\Users\web2py-src\gluon\restricted.py", line 227, in restricted
    exec ccode in environment
  File "C:/Users/web2py-src/applications/draft/controllers/question.py", line 96, in <module>
  File "C:\Users\web2py-src\gluon\globals.py", line 417, in <lambda>
    self._caller = lambda f: f()
  File "C:/Users/web2py-src/applications/draft/controllers/question.py", line 68, in printExam
    font.rtl = True
AttributeError: 'Font' object attribute 'rtl' is read-only

It would be nice if you took the trouble to indent your code correctly. — Mad Physicist, Feb 01 '17 at 16:57
Do you experience an issue if you don't do `font.rtl = True`? — Mad Physicist, Feb 01 '17 at 17:08
Seems like that line is not necessary if the value is already `True`. — Mad Physicist, Feb 01 '17 at 17:09
Yes, when i remove font.rtl = True, the text displayed with LTR direction — User, Feb 01 '17 at 17:10
Very odd. Where exactly is the error being raised? Could you provide a full traceback? — Mad Physicist, Feb 01 '17 at 17:11
Could it be because you are using a default font for the run? — Mad Physicist, Feb 01 '17 at 17:17
Yes, i didn't set a special font , should i ? and if yes how can i do that ? — User, Feb 01 '17 at 17:18
Hang on better idea. What version of the library are you using? — Mad Physicist, Feb 01 '17 at 17:21
Looking at the docs, you probably don't need to set a special Font. Looking at the code, I'd say that you don't either. Interesting problem. Perhaps @scanny has some input? — Mad Physicist, Feb 01 '17 at 18:10
No problem. I will check back on this question periodically because I am curious about how it will work out. Just when I though I had a grasp on how python-docx did the Python-to-xml mapping, I find something like this. — Mad Physicist, Feb 02 '17 at 15:33

No custom style has been defined on your paragraph so a default latent style is applied and this kind of style is read-only because it has no real definition in the document.

Apply a custom style on your run or your paragraph and you will be able to customize it. For a run, you have to create character style (WD_STYLE_TYPE.CHARACTER).

# create the document and the custom style
document = Document()
mystyle = document.styles.add_style('mystyle', WD_STYLE_TYPE.CHARACTER)
...
...
# apply the custom on the run
run.style = mystyle
font = run.font
font.rtl = True

Thanks a lot @DLDR for ur answer :) – User Feb 07 '17 at 13:05
@ Mad Physicist, this answer fixed the issue :) – User Feb 07 '17 at 13:06
,How can set the Text alignmnet to be right, i see in the documentation that it can be addded on the paragraph level only
Is there away to set the style for all statements in the documnet without define style per each one, – User Feb 07 '17 at 13:32
Ok, I haven't seen that in the documentation but you can also solve your problem by creating a paragraph style and set it to your paragraph. – Maxwell77 Feb 07 '17 at 13:37
Yes, but mt problem is to set the paragraph right aligned and RTL , couldn't mix them – User Feb 07 '17 at 13:51
For now, the solution I think which could work would be to create a base document in Ms Word and modifying the default normal style in it as needed. Then using Python-docx, I would use it as base document and inject all the new text in it. – Maxwell77 Feb 07 '17 at 14:46
