How can I access API data (Python, Requests) in specific cells of my HTML table?

Question

I've searched stackoverflow for hours and still can't find an answer so I would greatly appreciate your help! I'm building a metrics dashboard using an API and am stuck...

I'm using the requests Python HTTP library to help me retrieve sales data from an API. This is working great:

payload = {'data_source': 'daily'}
r = requests.get('https://api.appfigures.com/v1.1/sales/dates/2013-03-06/2013-03-14',        params=payload, auth=(api_key1, api_pass1))
data = json.loads(r.content) 

Output in JSON (1 day example):

{
    "2013-03-06": {
    "downloads": 1000,
    "updates": 20,
    "net_downloads": 100,
    "revenue": "20.00",
    "date": "2013-03-06"
},....

I created the structure of the dashboard using HTML:

    <tr class="dailytarget">
        <td class="metricname">Revenue</td>
        <td>NEED TO PUT REVENUE TOTAL HERE</td>
    </tr>

Now, the BIG QUESTION: how do I assign the table cells to values in the JSON output? For example, I need to sum up all of the "revenue" fields in the JSON output and store them in a cell in my table. How can I do this?

Answer 1

You can sum up all the json data by iterating through each of your json date information

If your api call is returning an array of objects:

from decimal import Decimal

total_revenue = sum(Decimal(x['revenue']) for x in data)

this takes every revenue value, converts it from a string to a Decimal type and then sums up all of those values.

Now at the very base all you have to do is insert the total_revenue into your html string

html_str = """
<tr class="dailytarget">
    <td class="metricname">Revenue</td>
    <td>{}</td>
</tr>""".format(total_revenue)

all the above does is use format to put the total revenue value into a string.

The tricky part now is, how are you going to present this HTML to a user? If you want to expose it as a website, it might be easiest to use any number of python web frameworks

Answer 2

days = json.loads(r.content)
total_revenue = 0.0
html = "<table>"
html += "<tr><th>Date</th><th>Revenue</th></tr>"
for day in days:
    day_revenue = float(day.get('revenue', 0))
    html += "<tr><td>%s</td><td>%f</td></tr>" % (day, day_revenue)
    total_revenue += day_revenue
html += '<tr><td colspan="2" style="text-align:right;">Total Revenue: %f</td><tr>' % (total_revenue)
html += "</table>"
print html
