Easily generate reports on the TagoIO platform using input form and analysis. You will learn:
There are some ways for generating reports, but today we are going to learn how to generate .CSV reports. For this task, the developer needs to already have a running application (device already setup, data on device’s bucket) and need to have decided which variables should be reported in the file. You also need to know some concepts like:
The reports can be generated on the TagoIO platform by just using a script for an analysis and a widget (we will use the Input Form widget but you can use others than that) to run the analysis. Now, let’s go for the implementation!
The script can be found here on Github and is named generateReports.js. You can check the following image if you are having trouble finding the script:
Copy the code from the file here on Github, and paste it on a new analysis within your TagoIO account. After that, set the following environment variables: device_token, dashboard_id and account_token. If you aren’t sure what values you should use on each of the variables, check the topics below, as there are additional explanations for each of them.
Device Token: it’s a token generated from the device you are using to work with the data you want to get on your report.
Dashboard ID: you need to get the ID of the dashboard you will use to implement this report system.
Account Token: token generated from the account you are using.
After you have inserted all the environment variables, you should have your environment variables tab like the following image:
Now, let’s go for the code!
The script generateReports.js is already operational and it’s just a matter of defining the variables to be included in the report. For this tutorial, I will choose the following variables:
humidity. Go to the script you have pasted on your report generation analysis and search for line 23. Line 23 should have something like that:
That is the line we want to change, you can see there is an array on the key named variable. You just need to insert the variables you want to report inside this array. For example, if you want the variable
battery. Your line should be like the following:
Another example; you want the variables
capacitance, so your line should be like the following:
That’s all you have to change on the code, but, there are some other lines you can change on the script to use the report as you want. You can customize the email that is sent for the user by changing what is written on lines 30 to 35. You can also customize the validation or customize the notification sent to the user in the same script; just take a look at the code and you should find everything that you want to customize. After that, let’s create the widget for our report generation system.
This is, by far, the easiest part of the tutorial. We have only four steps to follow here:
We are going to create a widget that will have an input for the user to insert the email, and after the email is inserted, the user will click on the button “Generate Report” to receive the link for the report on his email along with a validation on the widget giving the feedback to the user. To create this, just select the dashboard you want to have a report generation system on, and create an input form. On the input form, you should use two variables named email and validation. Like the following image:
After that, go to the field configurations of the widget and set the type of email as Text and the type of the validation as Validation. Like the image:
Now, go to the user control and select the report generation analysis you created before to the field Run analysis when submitting form. Like the image bellow:
You can also customize the text of the submit button and other options on the widget. But you only need what is written on this tutorial to get the report generations working. Check the following example using our report system in action!
That’s it for generating reports! Try to use it and check the report you will receive in your email. You can customize, make improvements and make any other changes with the script and widget. If you had any troubles during the tutorial leave your comments here and I will be happy to help you
