पर बहुत बड़ा मैं रिपोर्टलाब का उपयोग कर अपना पहला प्रोग्राम कर रहा हूं, जहां मुझे पहले से पता नहीं है कि पेज ब्रेक गिर जाएगा और मुझे परेशानी हो रही है। चीजों को सरल रखने के लिए मैं SimpleDocTemplate का उपयोग कर रहा हूं। मेरे flowables कुछ इस तरह दिखाई:ReportLab लेआउट त्रुटि: पृष्ठ
flowables = [Paragraph("Some title", style=headerParagraphStyle),
Spacer(0, 10),
Paragraph("first paragraph", style=bodyParagraphStyle),
Paragraph("second paragraph", style=bodyParagraphStyle),
...
Paragraph("nth paragraph", style=bodyParagraphStyle),
PageBreak(),
Paragraph("Some title", style=headerParagraphStyle),
Spacer(0, 10),
Paragraph("first paragraph", style=bodyParagraphStyle),
Paragraph("second paragraph", style=bodyParagraphStyle),
...
Paragraph("mth paragraph", style=bodyParagraphStyle),
PageBreak(),
...]
जब मैं निर्माण मेरी पीडीएफ सब कुछ के रूप में इतने लंबे समय ठीक हो जाता है मेरी n या m या हालांकि कई शरीर पैराग्राफ एक पृष्ठ पर फिट है, लेकिन अगर वे पर चलाया, मैं की तरह एक त्रुटि प्राप्त निम्नलिखित:
reportlab.platypus.doctemplate.LayoutError: Flowable <Paragraph at 0xb79800 frame=normal>20th paragraph: too large on page 3
क्यों यह मेरे लिए होता रहता है के लिए एक अच्छा कारण खोजने नहीं कर पा रहे। कोई सुझाव? यह तब भी करता है जब मैं पेजब्रेक्स() को हटा देता हूं। सभी पैराग्राफ अपेक्षाकृत कम हैं, ज्यादातर एक वाक्य/रेखा से अधिक है।
ईटीए: मैं कोड (छीन नाबालिग पहचानकर्ता के साथ) के सभी पोस्टिंग कर रहा हूँ कि मेरे लिए त्रुटि पैदा कर रहा है। मैंने इसे एक CSV फ़ाइल पढ़ने के लिए परिवर्तित कर दिया है, इसलिए मैंने अपनी सामग्री भी पोस्ट की है। सटीक त्रुटि है कि इस कोड जब मैं इसे चलाने के मेरे लिए उत्पन्न करता है:
Traceback (most recent call last):
File "./spice_dev.py", line 355, in
departmentReportDoc.build(eachDepartment.report, onFirstPage=onReportPage, onLaterPages=onReportPage)

reportlab.platypus.doctemplate.LayoutError: Flowable Additional comments and suggestions for improvement: too large on page 3
कुछ डिबगिंग काम से पता चलता है कि त्रुटि इस पैरा का परिणाम है (हालांकि यह अन्य flowables हो सकता है, सामग्री की लंबाई के आधार पर) की कोशिश कर रहा विभाजित, स्थगित किया जा रहा है, और फिर भी handle_frameEnd() पर कॉल के बाद विभाजित नहीं किया जा सकता है। सुझाव?
