Working with metamask, I have these two functions, which (for the most part) have almost identical calls to a smart contract:
localContract.methods
.presaleMint(window.ethereum.selectedAddress, ipfs)
.send({
from: window.ethereum.selectedAddress,
value: web3.utils.toWei(price * amount + "", "ether"),
gas: 240000 * (100 - amount * 4) / 100 * amount
})
localContract.methods.togglePresale().send({
from: window.ethereum.selectedAddress,
gas: 800000
})
The main difference I see is that the first function has params.
My question though is, why does metamask give the name of the called function for the second, but not the first? (first only shows 'Contract Interaction')
I can see that this was raised on metamask git years ago, i'm just surprised it's still set this way...

MetaMask uses a dictionary that translates function selector (0x and the first 8 hex characters of the data field) into a human-readable name.
If MM doesn't find the function selector in the dictionary, they use a generic label "Contract Interaction".
How to add your function selector (of the presaleMint() function) to their dictionary: https://docs.metamask.io/guide/registering-function-names.html#verify

I want to send the spool generated by a Smart Form, by email as attachment in TXT format.
The issue is to get the spool in a TXT format, without technical stuff, just the characters in the form.
I have used the function module RSPO_RETURN_SPOOLJOB for getting it, but it returns a technical format like this:
//XHPLJIIID 0700 00000+00000+

I want something as follows, without the technical stuff:
Dear Customer,

This is the code I have used :
PARAMETERS spoolnum type TSP01-RQIDENT.
DATA spool_contents type soli_tab.
CALL FUNCTION 'RSPO_RETURN_SPOOLJOB'
exporting
rqident = spoolnum
tables
buffer = spool_contents
exceptions
others = 1.
If the parameter DESIRED_TYPE is not passed or has the value 'OTF', and the spool is of type SAPscript/Smart Form, the function module returns the technical format you have experienced.
Instead, you should use the parameter DESIRED_TYPE = 'RAW' so that all the technical stuff is interpreted and the form is returned as text, the way you request, as follows :
CALL FUNCTION 'RSPO_RETURN_SPOOLJOB'
exporting
rqident = spoolnum
desired_type = 'RAW'
tables
buffer = spool_contents
exceptions
others = 1.
How do I give a name to my flows?
I currently see messages in the console (using dev tools) like:
action '<unnamed flow> - runid: 3 - init'
index.js:1 action '<unnamed flow> - runid: 3 - yield 0'
My code (in typescript):
fetchMetricData = flow( function * (this: MetricDataStore) {
const responseJson:IMetrics[] = yield Http.post("/metrics");
this.metrics = responseJson;
});
According to following text found in MobX Api Reference · MobX page:
Tip: it is recommended to give the generator function a name, this is the name that will show up in dev tools and such
Unfortunately, this is the only way to set the name (I use LiveScript and can't set names to function expressions while defining it).
In your case, you can turn your unnamed function expression into a named one. If you ever face another situation where you can't, you could also use Object.defineProperty(myFunction, 'name', {value: 'myExplicitName'}).
You can find the culprit in the code: mobx/flow.ts at master · mobxjs/mobx.
I am working on my own directory for my purchases of cryptocurrencies.
I am getting prices of BTC, ETH, and LTC via API, then I created a component for each of my punched coin, so then I want to calculate current price (ownedCoins * currentPrice).
So in my $root I have { eth: 324.233, btc: 2211.43, ltc: 41.341 }
Here is where I want to calculate it:
self.eur = response.data.sum[0].quantity * this.$root.ltc;
But I want to make this dynamic, so what I want to do is to create a dynamic variable. Something like that: self.eur = response.data.sum[0].quantity * this.$root.{this.coinName};
How would I do that?
I would read the State Management part of the VueJS docs then checkout the Vuex docs. Once your data store get even mildly more complex your method of managing it with your sample code will become overwhelming.
Your question doesn't have anything to do with vue, but just plain javascript. To access object variables in javascript you have 2 ways, using the dot notation or bracket notation (I call it array notation):
const car = { wheels: 4, seats: 5, horsepower: 145 };
console.log(car.wheels);
console.log(car['wheels']); //same result
So
this.$root[this.coinName];
will give you the result you are looking for.
I am using this code to query the api
function getResults(&$analytics, $profileId) {
// Calls the Core Reporting API and queries for the number of sessions
// for the last 30 days.
return $analytics->data_ga->get(
'ga:' . $profileId,
'30daysAgo',
'today',
'ga:sessionCount,ga:sessionDurationBucket,ga:users,ga:percentNewSessions,ga:bounceRate,ga:pageviews');
}
i get this error upon executing the code
Fatal error: Uncaught exception 'Google_Service_Exception' with
message 'Error calling GET
https://www.googleapis.com/analytics/v3/data/ga?ids=ga%3A114460017&start-date=30daysAgo&end-date=today&metrics=ga%3AsessionCount%2Cga%3AsessionDurationBucket%2Cga%3Ausers%2Cga%3ApercentNewSessions%2Cga%3AbounceRate%2Cga%3Apageviews:
(400) Unknown metric(s): ga:sessionCount, ga:sessionDurationBucket
anyone ever experience? I do not understand why it does not recognize those metrics when it is listed
https://developers.google.com/analytics/devguides/reporting/core/dimsmets#view=detail&group=user&jump=ga_sessioncount
If you look more closely into that documentation you will see that session count is not a metric, it's a dimension. The reason is that you want to be able to do breakdowns of metrics by session count (e.g. "show avg. duration of sessions for users with 3 sessions") and for that you need categorical data.
Even if you overlook the (not particularly distinctive) column heading in the table of contents (ga:sessionCount is in the "dimensions"-column) the fact that the datatype is a string would be a dead giveaway. Metrics are always numbers. Dimensions are always strings, even if they sometimes look like numbers.
Same goes for ga:sessionDurationBucket.
Look at this example from the documentation to see how dimensions are passed into the query via an array that holds optional parameters:
private function queryCoreReportingApi() {
$optParams = array(
'dimensions' => 'ga:source,ga:keyword',
'sort' => '-ga:sessions,ga:source',
'filters' => 'ga:medium==organic',
'max-results' => '25');
return $service->data_ga->get(
TABLE_ID,
'2010-01-01',
'2010-01-15',
'ga:sessions',
$optParams);
}
You'd need to construct a similar $optParams array:
$optParams = array(
'dimensions' => 'ga:sessionCount,ga:sessionDurationBucket'
');
and pass it to your query:
return $analytics->data_ga->get(
'ga:' . $profileId,
'30daysAgo',
'today',
$optParams,
'ga:users,ga:percentNewSessions,ga:bounceRate,ga:pageviews');
}
and remove the dimensions from the list of metrics.
Btw. Google has a wonderful documentation page on the difference between dimensions and metrics and how they are used in the reports.
I have Event model with following attributes (I quoted only problem related attributes), this model is filled periodically by API call, calling external service (Google Calendar):
colorid: number # (0-11)
event_start: datetime
event_end: datetime
I need to count duration of grouped events, grouped by colorid. I have Event instance method to calculate single event duration:
def event_duration
((event_end.to_datetime - event_start.to_datetime) * 24 * 60 ).to_i
end
Now, I need to do something like this:
event = Event.group(:colorid).sum(event_duration)
But this doesnot work for me, as long as I get error that event_duration column doesnot exists. My idea is to add one more attribute to Event model "event_duration", and count and update this attribute during Event record creation, in this case I would have column called "event_duration", and I might be ale to use sum on this attribute. But I am not sure this is good and "system solution", as long as I would like to have model data reflecting "raw" received data from API call, and do all math and statistics on the top of model data.
event_duration is instance method (not column name). error was raised because Event.sum only calculates the sum of certain column
on your case, I think it would be easier to use enumerable methods
duration_by_color_id = {}
grouped_events = Event.all.group_by(&:colorid)
grouped_events.each do |colorid, events|
duration_by_color_id[colorid] = events.collect(&:event_duration).sum
end
