[Flask] Passing MySQL values to different webpages

[Mazzei, Stephen Andrew]

Thanks Brian, but I was able to do this using Flask/session.

@app.route(‘/page1’)
def page1():
    session[‘var1’] = “Some value”
    return redirect(url_for(app.page2))

@app.route(‘/page2’)
def page2():
    return render_template(“template.html”, value2=session.get('val1', None))

Hi Stephen,

I believe that the best way to solve your problem will be to pass the data from page1 into page2 through the URI via GET request. In order to dynamically set the values, you will probably need to use Javascript. For example (with JQuery for syntactic convenience...)

mypage1.html:
<button id="go">Go to Page 2</button>
<script>
  $("#go").click( function() {
     target = "/mypage2?" + "key1=" + mydata[0] + "&key2=" + mydata[1]; // build the URI
     location.href = target; // redirect the page to that URL
   }
</script>

myapp.py:
@app.route("/mypage2")
def mypage2():
  data1 = request.args.get("key1")
  data2 = request.args.get("key2")
  return render_template("mypage2.html", key1=data1, key2=data2)

This isn't a complete by any means but hopefully gives enough to get you started... Let me know if you would like a better example and I'll try to put something up on github for you.

Good morning,

I am looking for help on a MySQL issue. I am currently running an query over a database and populating a table. The table contains items group units and then their values. I currently have the group unit as a link to that units own webpage.

On this webpage I would like to repost the same table information, per the unit, and then some additional information. How can I pass the query from the previous webpage to the next page without having to re-run the same query over and over again.

Thank you
