Python - jinja2 - putting all html from python into one PDF (not multiple)
I was given some great code from tuomastik on this site and changed how it works a bit. However, I spent a few hours editing it so that it prints one PDF, not several (one PDF, but each report started on a new page), but my HTML is not as good as I want to be, and i am stuck.
Code:
Html
<html>
<head>
<style type="text/css">
html, body {
width: 500px;
font-size: 12px;
background: #fff;
padding: 0px;
}
#my-custom-table {
width: 500px;
border: 0;
margin-top: 20px;
}
#my-custom-table td {
padding: 5px 0px 1px 5px;
text-align: left;
}
</style>
</head>
<body>
<table cellspacing="0" border="0" style="width:500px; border:0; font-size: 14px;">
<tr>
<td style="text-align:left;">
<b><span>Title of the PDF report - Row {{ row_ix + 1 }}</span></b>
</td>
<td style="text-align:right;">
<b><span>{{ date }}</span></b>
</td>
</tr>
</table>
<table cellspacing="0" border="0.1" id="my-custom-table">
{% for variable_name, variable_value in df.iteritems() %}
{% if loop.index0 == 0 %}
<tr style="border-top: 1px solid black;
border-bottom: 1px solid black;
font-weight: bold;">
<td>Variable name</td>
<td>Variable value</td>
</tr>
{% else %}
<tr>
<td>{{ variable_name }}</td>
<td>{{ variable_value }}</td>
</tr>
{% endif %}
{% endfor %}
</table>
</body>
</html>
Python
from datetime import date
import jinja2
import pandas as pd
from xhtml2pdf import pisa
df = pd.read_csv('data.csv', encoding='cp1252')
for row_ix, row in df.iterrows():
html = jinja2.Environment( # Pandas DataFrame to HTML
loader=jinja2.FileSystemLoader(searchpath='')).get_template(
'report_template.html').render(date=date.today().strftime('%d, %b %Y'),
row_ix=row_ix, df=row)
# Convert HTML to PDF
with open('report_row_%s.pdf' % (row_ix+1), "w+b") as out_pdf_file_handle:
pisa.CreatePDF(
src=html, # HTML to convert
dest=out_pdf_file_handle) # File handle to receive result
Can anyone please help? I know that I have to remove the for loop from the python file, but I don't know what to do with the html file.
I hate to ask, but I gave this good try, but I can't seem to get it to work when I mess around with loops in html.
Many thanks
