I have begun to move from models, modules, and controllers into actually
writing the view for my application. Now, I am at the point where I need to
loop through a Rows object, building a TR for each row. I wrote a version
that works by writing it in HTML, using {{=x}} where needed, but it looks
all cluttered and difficult to read. This is the original code that works:
{{extend 'layout.html'}}
<h1>Time Clock for {{=user.first_name}} {{=user.last_name}}</h1>
{{if len(rows) > 0:}}
{{
def get_day_of_year(the_date):
return the_date.timetuple().tm_yday
def full_date_name(the_date):
return the_date.strftime('%A, %B %d, %Y')
def time_string(the_date):
return the_date.strftime('%I:%M %p')
prev_day_of_year = None
table_open = False
for row in rows:
if get_day_of_year(row.calculated_start) != prev_day_of_year:}}
{{if table_open:}}
</tbody></table>
{{pass}}
<h4>{{=full_date_name(row.calculated_start)}}</h4>
<table><thead><tr><th>Time in:</th><th>Time
out:</th></tr></thead><tbody>
<tr><td>{{=time_string(row.calculated_start)}}</td><td>{{=time_string(row.calculated_end)}}</td></tr>
{{table_open = True}}
{{prev_day_of_year = get_day_of_year(row.calculated_start)}}
{{else:}}
<tr><td>{{=time_string(row.calculated_start)}}</td><td>{{=time_string(row.calculated_end)}}</td></tr>
{{pass}}
{{pass}}
</tbody></table>
<h5>Total hours worked this week: {{=hours_worked}}</h5>
{{else:}}
<h5>No time clock entries for this week.</h5>
{{pass}}
I know that web2py has HTML helpers like TABLE(), TR(), etc, but how would I
build a table in this way, while in a for loop? This is what I tried so far,
but it fails so horribly I don't even know where the error is:
{{extend 'layout.html'}}
<h1>Time Clock for {{=user.first_name}} {{=user.last_name}}</h1>
{{if len(rows) > 0:}}
{{
def get_day_of_year(the_date):
return the_date.timetuple().tm_yday
def full_date_name(the_date):
return the_date.strftime('%A, %B %d, %Y')
def time_string(the_date):
return the_date.strftime('%I:%M %p')
prev_day_of_year = None
tables = []
trs = None
for row in rows:
if get_day_of_year(row.calculated_start) != prev_day_of_year:
if trs is not None:
tables[] = (H4(full_date_name(row.calculated_start)),
trs)
trs = []
trs[] = TR((TD(time_string(row.calculated_start)),
TD(time_string(row.calculated_end))))
prev_day_of_year = get_day_of_year(row.calculated_start)
else:
trs[] = TR((TD(time_string(row.calculated_start)),
TD(time_string(row.calculated_end))))
for table in tables:
response.write(table[0])
response.write(TABLE(
(THEAD(
TR(
(TH('Time in:), TH('Time out'))
)
),
TBODY(
))
))
}}
<h5>Total hours worked this week: {{=hours_worked}}</h5>
{{else:}}
<h5>No time clock entries for this week.</h5>
{{pass}}
