Hi,
I have a main patient input page with 3 components on...
<div id="content">
<div id="patient_info" class="layout_block">
{{=LOAD('patient', 'patient_details.load', ajax=True,
target='patient_info')}}
</div>
<div id="phenotype_form" class="layout_block">
{{=LOAD('phenotype_form', 'phenotype_form.load', ajax=True,
target='phenotype_form')}}
</div>
<div id="patient_scan_history" class="layout_block">
{{=LOAD('patient_scan_history', 'patient_scan_history.load',
ajax=True, target='patient_scan_history')}}
</div>
</div>.
...and to work properly, 2 of those components (the first and third above)
need a patient id, which is held in an input box (id="patient_id") on a
form, in patient_details.load (first component above) ...
<form id="patient_form">
<fieldset>
<table>
<tr>
<td> Patient ID (or leave empty for new patient): <input name=
"patient_id" id="patient_id" value={{=(patient_id or '')}}></td>
<td><input type="submit" value="Search Patient"></td>
<div id="clearcanvas_target">{{=study_response}}</div>
</tr>
<tr>
<td> Source: <input type='text' name='source' id='source'
value={{=patient_source}}>
Diagnosis: <input type='text' name='diagnosis' id=
'diagnosis' value={{=patient_diagnosis}}>
</td>
</tr>
</table>
</fieldset>
</form>
... and here is the part of patient_load.py, where I can get the patient_id
from request.vars.patient_id, and set a global variable session.patient_id
to have the same value.
if(request.vars.patient_id):
session.patient_id = int(request.vars.patient_id)
study_response = open_patient_images_clearcanvas(session.patient_id)
db = get_db()
rows = db((db.patient.patient_pk == db.patient_diagnosis.patient_fk)
& (db.patient_diagnosis.diagnosis_fk == db.diagnosis.diagnosis_pk) & (db.
patient.patient_pk == session.patient_id)).select(db.patient.source, db.
diagnosis.diagnosis_name)
...
The above patient_load component works OK.
BUT the third component, where I wish to load patient history, and which
also requires a patient_id, wont work properly, as the session.patient_id
above is not updated until i press refresh.
Here is my main patient_scan_history.py function
def patient_scan_history():
patient_id = 1
if(session.patient_id):
patient_id = session.patient_id
db = get_db()
patient_scans = Patient_scan_history(db, patient_id)
patient_scan_history = patient_scans.get_patient_scan_history()
else:
return dict(html_table = None)
html_table = TABLE( TR(*[TH(*headers) for headers inpatient_scan_history
['headers']]), *[TR(*rows) for rows in patient_scan_history['table']])
return dict(html_table=html_table)
... and my patient_scan_history.load
<form>
<fieldset>
{{=html_table}}
</fieldset>
</form>
So from the users point of view, the top component information loads as
soon as there is a valid patient id and the submit ('search patient')
button is pressed. But the third component is not updated at this point,
and only shows the correct patient history table when the refresh button is
clicked.
As the 3rd component is reliant on a patient ID from the 1st component, I'm
guessing maybe it should not be a component ??
Can anyone help???
Regards
A
