python - Unable to set the value of a SelectControl element -


i trying machine-parsable bus schedule data submitting form mechanize.

however, stymied mechanize syntax setting 

import mechanize br = mechanize.browser() br.open("http://www.planibus.sto.ca/hastinfoweb/starttimetableform.aspx") br.select_form(name="timetablequeryform") br["routedirectiondynamiccombobox$combobox_input"] = "10 ottawa" # works fine, it's textcontrol br["datepicker$daysdropdownlist"] = ["3"] # selectcontrol ### mechanize._form.itemnotfounderror: insufficient items name '3'

mechanize._form.itemnotfounderror: insufficient items name '3' looks needs list, when enter more 1 item in list (which makes little sense, given date picker) get:

mechanize._form.itemcounterror: single selection list, must set sequence of length 0 or 1

i thought original ["3"] sequence of length 1?

thanks attention. i'm missing obvious...

edit: note '3' above 1 value, , web site allows values next 2 weeks in ui, depending on when see this, list of allowable values change. substitute '3' 1 of allowable values... still doesn't work me...

3 isn't 1 of available select options, options see are

<option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> <option value="11">11</option> <option value="12">12</option> <option value="13">13</option> <option value="14">14</option> <option value="15">15</option> <option value="16">16</option> <option value="17">17</option> <option value="18">18</option>

so try br["datepicker$daysdropdownlist"] = ["4"] , code should work.

edit: i've tried looking @ page in question mechanize, try this

import mechanize br = mechanize.browser() br.open("http://www.planibus.sto.ca/hastinfoweb/starttimetableform.aspx") br.select_form(name="timetablequeryform") select = br.form.controls[8] # datepicker$daysdropdownlist select.possible_items() >>> []

there aren't options, imagine javascript used populate them after page has loaded. unfortunatly mechanize doesn't support javascript, try using selenium webdriver scrape data need.

sql - text truncated using perl DBI insert -

the problem dbi 's insert leaves long string truncated when inserting ms sql server. here codes: my $insert = $dbh->prepare("insert my_table (field_1, field_2) values (?, ?)"); $insert->execute($value_1, $value_2); where field_2 has data type of varchar(100) , $value_2 text string of 90 characters spaces no other special characters. after statement executed, no error raised, checked database , apparently actual inserted $value_2 truncated @ 80th character, in middle of regular english word (i.e. not special character). i've tried alter data type of field_2 varchar(150) , text . i've used $dbh->quote($value_2) in place of $value_2 . didn't help. why happening? should do? thx!! if using freetds bug identified in freetds mailing list. see freetds silently truncating text/varchar/etc fields 80 characters , http://lists.ibiblio.org/pipermail/freetds/2011q2/026943.html , http://lists.ibiblio.org/pipermail/freetds/2011q2/026...
