【问题描述】:
我正在使用 Python 2.7.6 和 Django 1.5.5。 如何在 SimpleDocTemplate 中写一行?
我正在尝试这个:
@login_required
def report(request):
rep = Report(request.user.username + "_cities.pdf")
# Title
rep.add_header("Cities")
line = Line(0, 100, 500, 100)
rep.add(line)
# Body
columns = ("City")
cities = [(p.name) for p in City.objects.all()]
table = Table([columns] + cities, style=GRID_STYLE)
table.hAlign = "LEFT"
table.setStyle([('BACKGROUND', (1, 1), (-2, -2), colors.lightgrey)])
rep.add(table)
rep.build()
return rep.response
Line() 是 from reportlab.graphics.shapes import Line。
Report 类只是 SimpleDocTemplate 的包装类:
class Report:
styles = None
response = None
document = None
elements = []
def __init__(self, report_file_name):
self.styles = styles.getSampleStyleSheet()
self.styles.add(ParagraphStyle(name='Title2',
fontName="Helvetica",
fontSize=12,
leading=14,
spaceBefore=12,
spaceAfter=6,
alignment=TA_CENTER),
alias='title2')
self.response = HttpResponse(mimetype="application/pdf")
self.response["Content-Disposition"] = "attachment; filename=" + report_file_name
self.document = SimpleDocTemplate(self.response, topMargin=5, leftMargin=2, rightMargin=1, bottomMargin=1)
self.document.pagesize = portrait(A4)
return
def add_header(self, header_text):
p = Paragraph(header_text, self.styles['Title2'])
self.elements.append(p)
def add(self, paragraph):
self.elements.append(paragraph)
def build(self):
self.document.build(self.elements)
当我调用报告函数时,我收到错误消息:
Line instance has no attribute 'getKeepWithNext'
当我删除/注释带有Line() 的行时,不会发生错误。
你能帮帮我吗? 那行怎么写?
