Trying to use Mako template in python to render json data

Question

I'm not understanding the documentation on using Mako templates in python. I have a python file and I have the following code:

import json, requests, urllib2
from mako.template import Template
from mako.lookup import TemplateLookup
from pylons.templating import render_mako as render

url="www.data&format=json"
response = urllib2.urlopen(url)
data = json.load(response)
return (Template("hello Luisito! Here is the data: ${data}!").render(json_data=data))

could someone provide me with some more detail on how to render this json data into a webpage using the mako template? do i need another file with the template? if so, how?

What part of your question here needs an HTML template library that string formatting cannot achieve? — OneCricketeer, Nov 14 '16 at 22:27
What web framework are you using? You should go read the documentation on that. The `def navigation(self):` on its own is doing nothing. — OneCricketeer, Nov 14 '16 at 22:31
@cricket_007 essentially the input will be a json object and i would like to use a template to display the results of that object — Luisito, Nov 14 '16 at 22:37
As HTML, or just a JSON string? You can `print(data)`. I do not see a need for Mako in your question. Do you even have a webserver running to display HTML onto a page? — OneCricketeer, Nov 14 '16 at 22:42
@cricket_007 I've made edits to the code thus far, elimanating the navigation method. I'm not sure how to get the server running — Luisito, Nov 14 '16 at 22:44
Mako is not a Server. I think you should [keep reading the documentation](http://docs.makotemplates.org/en/latest/usage.html#using-file-based-templates). Regarding the server, forget Mako, use [Jinja & Flask](http://flask.pocoo.org/docs/0.11/tutorial/views/) — OneCricketeer, Nov 14 '16 at 22:45

You need to add a variable for the json data:

url="www.data&format=json"
response = urllib2.urlopen(url)
data = json.load(response)   
from mako.template import Template
print(Template("hello Luisito! Here is the data: ${json_data}!").render(json_data=data))

I think OP wants to render the HTML template. This just prints to the console – OneCricketeer Nov 14 '16 at 22:28
@rofls how would i display that response on the mako template though? – Luisito Nov 14 '16 at 22:29
@cricket_007 that is correct, do you know how to render to html template? – Luisito Nov 14 '16 at 22:30

mylookup = TemplateLookup(directories=['./html'], output_encoding='utf-8', encoding_errors='replace')

def browseLocal(webpageText, filename):
    '''Start your webbrowser on a local file containing the text
    with given filename.'''
    import webbrowser, os.path
    strToFile(webpageText, filename)
    # webbrowser.open("file:///" + os.path.abspath(filename)) #elaborated for Mac.

def strToFile(text, filename):
    """Write a file with the given name and the given text."""
    output = open(filename,"w")
    output.write(text)
    output.close()

def fileToStr(fileName): # NEW
    """Return a string containing the contents of the named file."""
    fin = open(fileName); 
    contents = fin.read();  
    fin.close() 
    return contents

f = open("data.json", "r")
data = f.read()
jsonData = json.loads(data)
list1 = jsonData["Records"]
for val in list1:
    pageName = val["pageName"]
    seoMetaData = val["seoMetaData"]
    logoImg = val["logoImg"]
    logoImgUrl = val["logoImgUrl"]
    description = val["description"]
    product = val["product"]
    category = val["category"]
    customerAccount = val["customerAccount"]

    template = mylookup.get_template(uri)
    htmlContent = template.render_unicode(name=pageName, seoMetaData=seoMetaData, logoImg=logoImg, logoImgUrl=logoImgUrl, description=description, product=product, category=category, customerAccount=customerAccount)
    browseLocal(htmlContent, pageName)
f.close()

I am trying this method as of now. Hope this helps – Arun Kamble Jul 23 '19 at 10:13 — Arun Kamble, Jul 23 '19 at 10:13
